是否可以在增量滑块上创建if / then语句? 这是代码:
<script>
$(function() {
$( "#slider" ).slider({
value:0,
min: 0,
max: 2,
step: 1,
slide: function( event, ui ) {
$( "#amount" ).val( "$" + ui.value );
}
});
$( "#amount" ).val( "$" + $( "#slider" ).slider( "value" ) );
});
</script>
</head>
<body>
<p id="amount">
<input type="text" id="amount" style="border:0; color:#f6931f; font-weight:bold;">
</p>
<div id="slider"></div>
换句话说,我有一个3个增量的滑块。当增量为min时,我希望它显示一个div(带有内容),并且在med和max两个其他div上。
我认为最好的方法是做一个if / then,但不确定如何去做。
解决方案?

使用change
事件:
$( "#slider" ).slider({
value:0,
min: 0,
max: 2,
step: 1,
slide: function( event, ui ) {
$( "#amount" ).val( "$" + ui.value );
},
change: function( event, ui) {
if (ui.value == 0) {
$("#mindiv").show();
} else {
$("#mindiv").hide();
}
}
});

处理change
事件
$( "#slider" ).on( "slidechange", function( event, ui ) {
var value = $( "#slider" ).slider( "value" );
if(value==1){
}else{
}
});
