目前我有一个检查列表，一旦点击一个复选框就会更新进度条，但是，我希望进度条根据复选框上的百分比更新。我花了几个小时寻找解决方案并尝试不同的事情，但没有运气。有任何帮助或建议吗？

更新了 FIDDLE
不是计算已选中复选框的数量，而是将已选中复选框的值加起来：
//calculate percentage
perc = 0;
$("#theList input[type=checkbox]:checked").each(function( index ) {
perc += parseInt($(this).val());
});
if (perc < 15) {
$("#progress").css('background', 'red');
} else if (perc < 30) {
$("#progress").css('background', 'orange');
} else if (perc < 60) {
$("#progress").css('background', 'yellow');
} else {
$("#progress").css('background', 'lime');
}
$("#progress").css("width", perc + "%");
parseInt($(this).val())为您提供值的整数表示。
答案 1 :(得分：-1)
这里是codepen中的一个例子。
<form>
<p>
<input type="checkbox" name = "box1"/>
<input type="checkbox"name = "box2" />
<input type="checkbox" name = "box3"/>
</p>
</form>
<div class="progressbar-container">
<div class="progressbar-bar"></div>
<div class="progressbar-label"></div>
</div>
<div class = "ready"></div>
这是为此的JavaScript
$(document).ready(function() {
// get box count
var count = 0;
var checked = 0;
function countBoxes() {
count = $("input[type='checkbox']").length;
console.log(count);
}
countBoxes();
$(":checkbox").click(countBoxes);
// count checks
function countChecked() {
checked = $("input:checked").length;
var percentage = parseInt(((checked / count) * 100),10);
$(".progressbar-bar").progressbar({
value: percentage
});
$(".progressbar-label").text(percentage + "%");
}
countChecked();
$(":checkbox").click(countChecked);
});
通过CSS应用进度条的更改。
body { margin: 20px 50px; }
h1 { font-size: 1.5em; }
p { margin: 0; }
input[type="checkbox"] {
height: 20px;
width: 20px;
margin-right: 10px;
}
.ready { font-size: 1.5em; }
.ui-progressbar-value { background: lightgreen; }
.progressbar-container {
position: relative;
width: 350px;
}
.progressbar-bar {
height: 25px;
margin: 10px 0;
border-radius: 7px;
}
.progressbar-label {
position: absolute;
top: 2px;
left: 45%;
z-index: 2;
}
