PrimeNg 图标未显示（复选框和选择）

Question

Checked box and select sans icons.

I've added the primeicons library per: https://github.com/primefaces/primeng/wiki/Migration-Guide

However, something is still a muck, I can't get the icons with show up.

package.json:

...
"primeicons": "^1.0.0-beta.10",
"primeng": "6.1.2",

also have, not sure if relevant. Doesn't seem like it's overwriting the css but possible

"font-awesome": "4.7.0",
"@angular/material": "^6.4.7",

html:

<p-checkbox binary="true" label="Match Note"></p-checkbox>

html showing icon class - from dev tools:

<span class="ui-chkbox-icon ui-clickable pi pi-check" ng-reflect-klass="ui-chkbox-icon ui-clickable" ng-reflect-ng-class="[object Object]"></span>

css - from dev tools:

Answer 1

You can also include primeng.css, theme and primengicons under 'styles' section in angular.json.

"styles": [
     "../node_modules/primeng/resources/primeng.min.css",
     "../node_modules/primeng/resources/themes/nova-light/theme.css",
     "../node_modules/primeicons/primeicons.css"
]

Answer 2

尝试在 style.css 文件中添加导入

@import '~primeicons/primeicons.css';

Answer 3

change span font family in style.css to

span{
    font-family:'primeicons' !important
}

Answer 4

If you are still not able to see the icons and styling after applying the suggestions in the accepted answer, try adding the css entries into your styles.scss file, that is what it took in my case.

@import  "~primeicons/primeicons.css";
@import  "~primeng/resources/themes/saga-blue/theme.css";
@import  "~primeng/resources/primeng.min.css";
@import  "~primeflex/primeflex.css";

Answer 5

This might not be directly relevant, but I was trying to solve a similar problem with Search and placing a search icon within the text input.

The problem for me was z-index; the icon was there, but it was hidden behind the search input box!!

So setting the icon's z-index via CSS solved the issue (in my case, to 1).

.pi .pi-search {
z-index: 1;
}

Answer 6

In case someone still facing this issue, do check webpack loader config.

For me the issue was related to webpack loader:

After updating my code of webpack module loader from :

            {
                test: /\.(png|woff|woff2|eot|ttf|svg)$/, 
                use: ["url-loader", "file-loader"]
            }

to:

            {
                test: /\.(png|woff|woff2|eot|ttf|svg)$/,
                loader: 'url-loader'
            },
            {
                test: /\.(ico|jpe?g|png|gif|webp|svg|mp4|webm|wav|mp3|m4a|aac|oga)(\?.*)?$/,
                loader: "file-loader"
            }

Icons started loading properly.

You have to add DropdownModule and this one CheckboxModule and then this section to your styles.css file.

@import "~primeicons/primeicons.css";
@import "~primeng/resources/themes/saga-blue/theme.css";
@import "~primeng/resources/primeng.min.css";
