Question

我知道这应该很简单，但我想检查进度条是否等于100％。如果有的话，我似乎无法触发警报。

＆＃13;

var bar = $('.progress-bar').text(val);
var val = percentage + '%';
var percentage=1;
   if(bar == 100){
       alert("100");
   }

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="bar">
<div class="progress">
<div class="progress-bar progress-bar-warning progress-bar-striped" role="progressbar" aria-valuenow="10"aria-valuemin="0" aria-valuemax="100" style="width:10%">100%</div>
</div>
</div>

＆＃13;

Answer 1

$(document).ready(function(){

    var percentage = someFunctionToGetPercentage();

    $('.progress-bar').text(percentage + '%');

    if (parseInt($('.progress-bar').text()) == 100) { // or $('.progress-bar').text() == '100%'
        alert(100);
    }
});
