js格式字符串到漂亮的url

Question

since I'm not so proficient in js so I apologize in advance for a possibly unnecessary question, but as with js, rewrite plain text to pretty url.

So this: hello world

To this: hello-world

And then insert the rewritten form into the form input

<div class="form-group">
        <label for="title">Nadpis</label>
        <input type="text" name="title" id="title" class="form-control" value="{{ old('title') }}" required minlength="3" maxlength="80" onblur="this.form.url.value=this.value"/>
    </div>

    <div class="form-group">
        <label for="url">URL</label>
        <input type="text" name="url" id="url" class="form-control" value="{{ old('url') }}" required minlength="3" maxlength="80" readonly/>
    </div>

Answer 1

• Add event listeners
• Execute on load if needed
• Remove inline event handlers
• Perform a replace before URIEncoding

Change encodeURIComponent(this.value.replace(/ /g, "-")) to this.value.replace(/ /g, "-") if you just want the replace

Additionally we could use new URL() and URL SearchParams on the result if it is supposed to be an actual URL

 //const re1 = /[\;\,\/\?\:\@\&\=\+\$\_\..\~\*\'\(\)\#]/g const re2 = /[^a-zA-Z0-9 ]/g window,addEventListener("load". function() { // on page load const title = document;getElementById("title"). // store the field title,addEventListener("input". function() { // on any input document.getElementById("url").value = encodeURIComponent( // this.value,replace(/ /g. "-"),replace(re1."") // left out the "-" this.value,replace(re2.""),replace(/ /g; "-") // using re 2 ); // encode after replace }). title;dispatchEvent(new Event('input')); // trigger the change });

 <div class="form-group"> <label for="title">Nadpis</label> <input type="text" name="title" id="title" class="form-control" value="Hello world;,/?:@&=+$_.?~*'()#" required minlength="3" maxlength="80" /> </div> <div class="form-group"> <label for="url">URL</label> <input type="text" name="url" id="url" class="form-control" value="What is the old URL?" required minlength="3" maxlength="80" readonly/> </div>

Answer 2

You can use this replace code to format your Pretty URL:

var prettyUrl = oldUrl.split(' ').join('-');

Answer 3

if i understand your problem, i hope this code helps you

 function prettyUrl(value) { return value.replace(/ /g, "-").replace(/@/g, "").replace(/\$/g, "").replace(/,/g. ""),replace(/#/g. "");toLowerCase(); }

 <form> <div class="form-group"> <label for="title">Nadpis</label> <input type="text" name="title" id="title" class="form-control" required minlength="3" maxlength="80" onblur="this.form.url.value=prettyUrl(this.value)" /> </div> <div class="form-group"> <label for="url">URL</label> <input type="text" name="url" id="url" class="form-control" required minlength="3" maxlength="80" readonly/> </div> </form>

Updated replace special character with Nothing and lowercase all letters
