我尝试做简单的if / else语句,例如“如果滑块上的值为100,则将带有一些文本的p标签附加到英里类”。我知道这很简单,但是我查看了jQuery文档并没有找到适合我的解决方案。
HTML:
<html><head>
<meta charset="utf-8">
<title></title>
</head>
<body>
<div class="wrapper">
<div class="miles"></div>
<div class="battery-slider">
<input class="slider-range" type="range" value="0" min="75" max="250" step="25">
<span class="slider-value">0</span>
</div>
</div>
</body>
</html>
JavaScript的:
var rangeSlider = function(){
var slider = $('.battery-slider'),
range = $('.slider-range'),
value = $('.slider-value');
miles = $('.miles');
slider.each(function(){
value.each(function(){
var value = $(this).prev().attr('value');
$(this).html(value);
});
range.on('input', function(){
$(this).next(value).html(this.value);
});
});
if ( $(range).val(value) == 100 ) {
$(miles).append( "<p>Pass</p>" );
}
else {
$(miles).append( "<p>Fail</p>" );
}
};
rangeSlider();

您的要求有点不清楚,但也许您正在寻找类似的东西:
var rangeSlider = function(){
var slider = $('.battery-slider'),
range = $('.slider-range'),
value = $('.slider-value');
miles = $('.miles');
slider.each(function(){
value.each(function(){
var value = $(this).prev().attr('value');
$(this).html(value);
});
range.on('input', function(){
if ( this.value == 100 ) {
$(miles).append( "<p>Pass</p>" );
}
else {
$(miles).append( "<p>Fail</p>" );
}
$(this).next(value).html(this.value);
});
});
};
rangeSlider();
