在占位符中使用 Font Awesome 图标

Question

Is it possible to use Font Awesome Icon in a Placeholder? I read that HTML isn't allowed in a placeholder. Is there a workaround?

placeholder="<i class='icon-search'></i>"

Answer 1

If you're using FontAwesome 4.7 this should be enough:

 <link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/> <input type="text" placeholder="&#xF002; Search" style="font-family:Arial, FontAwesome" />

A list of hex codes can be found in the Font Awesome cheatsheet . However, in the lastest FontAwesome 5.0 this method does not work (even if you use the CSS approach combined with the updated font-family ).

Answer 2

You can't add an icon and text because you can't apply a different font to part of a placeholder, however, if you are satisfied with just an icon then it can work. The FontAwesome icons are just characters with a custom font (you can look at the FontAwesome Cheatsheet for the escaped Unicode character in the content rule. In the less source code it's found in variables.less The challenge would be to swap the fonts when the input is not empty. Combine it with jQuery like this .

<form role="form">
  <div class="form-group">
    <input type="text" class="form-control empty" id="iconified" placeholder="&#xF002;"/>
  </div>
</form>

With this CSS:

input.empty {
    font-family: FontAwesome;
    font-style: normal;
    font-weight: normal;
    text-decoration: inherit;
}

And this (simple) jQuery

$('#iconified').on('keyup', function() {
    var input = $(this);
    if(input.val().length === 0) {
        input.addClass('empty');
    } else {
        input.removeClass('empty');
    }
});

The transition between fonts will not be smooth, however.

Answer 3

I solved with this method:

In the CSS I used this code for the fontAwesome class :

.fontAwesome {
  font-family: 'Helvetica', FontAwesome, sans-serif;
}

In the HTML I have added the fontawesome class and the fontawesome icon code inside the placeholder:

<input type="text" class="fontAwesome" name="emailAddress" placeholder="&#xf0e0;  insert email address ..." value="">

You can see in CodePen .

Answer 4

@Elli's answer can work in FontAwesome 5, but it requires using the correct font name and using the specific CSS for the version you want. For example when using FA5 Free, I could not get it to work if I included the all.css, but it worked fine if I included the solid.css:

 <link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.8.1/css/solid.css"> <input type="text" placeholder="&#xF002; Search" style="font-family: Arial, 'Font Awesome 5 Free'" />

For FA5 Pro the font name is 'Font Awesome 5 Pro'

Answer 5

Where supported, you can use the ::input-placeholder pseudoselector combined with ::before .

See an example at:

I was just working on this and came across this article, from which I modified this stuff:

Answer 6

I am using Ember (version 1.7.1) and I needed to both bind the value of the input and have a placeholder that was a FontAwesome icon. The only way to bind the value in Ember (that I know of) is to use the built in helper. But that causes the placeholder to be escaped, "&#xF002" just shows up just like that, text.

If you are using Ember or not, you need to set the CSS of the input's placeholder to have a font-family of FontAwesome. This is SCSS (using Bourbon for the placeholder styling ):

    input {
      width:96%;
      margin:5px 2%;
      padding:0 8px;
      border:1px solid #444;
      border-radius: 14px;
      background: #fff;
      @include placeholder {
        font-family: 'FontAwesome', $gotham;
      }
    }

If you are just using handlebars, as has been mentioned before you can just set the html entity as the placeholder:

<input id="listFilter" placeholder="&#xF002;" type="text">

If you are using Ember bind the placeholder to a controller property that has the unicode value.

in the template:

{{text-field
  id="listFilter"
  placeholder=listFilterPlaceholder
  value=listFilter}}

on the controller:

listFilter: null,
listFilterPlaceholder: "\uf002"

And the value binding works fine!

Answer 7

Use placeholder="" in your input. You can find unicode in FontAwesome page http://fontawesome.io/icons/ . But you have to make sure add style="font-family: FontAwesome;" in your input.

Answer 8

Anyone wondering about a Font Awesome 5 implementation:

Do not specify a general "Font Awesome 5" font family, you need to specifically end with the branch of icons you're working with. Here I am using the branch "Brands" for example.

<input style="font-family:'Font Awesome 5 Brands' !important" 
       type="text" placeholder="&#xf167">

More detail Use Font Awesome (5) icon in input placeholder text

Answer 9

I know this question it is very old. But I didn't see any simple answer like I used to use.

You just need to add the fas class to the input and put a valid hex in this case &#xf002 for Font-Awesome's glyph as here <input type="text" class="fas" placeholder="&#xf002" />

You can find the unicode of each glyph in the official web here .

This is a simple example you don't need css or javascript.

 input { padding: 5px; }

 <link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.6.3/css/all.css" integrity="sha384-UHRtZLI+pbxtHCWp1t77Bi1L4ZtiqrqD80Kn4Z8NTSRyMA2Fd33n5dQ8lWUE00s/" crossorigin="anonymous"> <form role="form"> <div class="form-group"> <input type="text" class="fas" placeholder="&#xf002" /> </div> </form>

Answer 10

I do this by adding fa-placeholder class to input text:

<input type="text" name="search" class="form-control" placeholder="&#xF002;" />

so, in css just add this:

.fa-placholder { font-family: "FontAwesome"; }

It works well for me.

Update:

To change font while user type in your text input, just add your font after font awesome

.fa-placholder { font-family: "FontAwesome", "Source Sans Pro"; }

Answer 11

Ignoring the jQuery this can be done using ::placeholder of an input element.

<form role="form">
  <div class="form-group">
    <input type="text" class="form-control name" placeholder="&#xF002;"/>
  </div>
</form>

The css part

input.name::placeholder{ font-family:fontAwesome; font-size:[size needed]; color:[placeholder color needed] }

input.name{ font-family:[font family you want to specify] }

THE BEST PART: You can have different font family for placeholder and text

Answer 12

I've solved the problem a bit differently and it works with any FA icon through html code. Instead of all these difficulties with placeholder my solution is:

1. To place an icon in the usual manner

HTML
<i class="fas fa-icon block__icon"></i>
<input type="text" name="name" class="block__input" placeholder="Some text">

CSS
.block__icon {
  position: absolute;
  margin: some-corrections;
}
.block__input {
  padding: some-corrections;
}

2. Then adjust placeholder's text (it's personal for everyone, in my case an icon was just before the text)

HTML
<!-- For example add some spaces in placeholder, to make focused cursor stay before an icon -->
...placeholder="    Some text"...

3. Here is the problem that an icon is above the our input and blocks cursor to click so we should add one more line in our CSS

CSS
.block__icon {
  position: absolute;
  margin: some-corrections;

  /* The new line */
  pointer-events: none;
}

4. But an icon doesn't disappear together with placeholder so we need to fix it. And also this is the final version of my solution:

HTML
<i class="fas fa-icon block__icon"></i>
<input type="text" name="name" class="block__input" placeholder="    Some text">

CSS
.block__icon {
  position: absolute;
  z-index: 2; /* New line */
  margin: some-corrections;
}
.block__input {
  position: relative; /* New line */
  z-index: 2; /* New line */
  padding: some-corrections;
}
/* New */
.block__input:placeholder-shown {
    z-index: 1;
}

It's harder than I thought before, but I hope I've helped anyone with this.

Answer 13

There is some slight delay and jank as the font changes in the answer provided by Jason. Using the "change" event instead of "keyup" resolves this issue.

$('#iconified').on('change', function() {
    var input = $(this);
    if(input.val().length === 0) {
        input.addClass('empty');
    } else {
        input.removeClass('empty');
    }
});

Answer 14

I added both text and icon together in a placeholder.

placeholder="Edit   "

CSS :

font-family: FontAwesome,'Merriweather Sans', sans-serif;

Answer 15

If you can / want to use Bootstrap the solution would be input-groups:

<div class="input-group">
 <div class="input-group-prepend">
  <span class="input-group-text"><i class="fa fa-search"></i></span>
  </div>
 <input type="text" class="form-control" placeholder="-">
</div>

Looks about like this: input with text-prepend and search symbol

Answer 16

Teocci solution is as simple as it can be, thus, no need to add any CSS, just add class="fas" for Font Awesome 5, since it adds proper CSS font declaration to the element.

Here's an example for search box within Bootstrap navbar, with search icon added to the both input-group and placeholder (for the sake of demontration, of course, no one would use both at the same time). Image: https://i.imgur.com/v4kQJ77.png "> Code:

<form class="form-inline my-2 my-lg-0">
    <div class="input-group mb-3">
        <div class="input-group-prepend">
            <span class="input-group-text"><i class="fas fa-search"></i></span>
        </div>
        <input type="text" class="form-control fas text-right" placeholder="&#xf002;" aria-label="Search string">
        <div class="input-group-append">
            <button class="btn btn-success input-group-text bg-success text-white border-0">Search</button>
        </div>
    </div>
</form>

Answer 17

Sometimes above all answer not woking, when you can use below trick

 .form-group { position: relative; } input { padding-left: 1rem; } i { position: absolute; left: 0; top: 50%; transform: translateY(-50%); }

 <link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.6.3/css/all.css"> <form role="form"> <div class="form-group"> <input type="text" class="form-control empty" id="iconified" placeholder="search"> <i class="fas fa-search"></i> </div> </form>

Answer 18

<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.6.3/css/all.css">
<form role="form">
  <div class="form-group">
    <input type="text" class="form-control empty" id="iconified" placeholder="search">
    <i class="fas fa-search"></i>
  </div>
</form>

.form-group {
  position: relative;
}
i {
  position: absolute;
  left: 0;
  top: 50%;
  transform: translateY(-50%);
  z-index: 999;
}
input {
  padding-left: 1rem;
}
