我正在尝试使用 jQuery 滑块的范围属性，以便滑块控件显示两个句柄，用户可以从中选择房地产的价格范围。我的代码是：
$("#price").slider({ range: true, minValue: 0, maxValue: 2000000,
change:
function(e, ui) {
var range = (Math.round(ui.range) * 10) + " to " + ui.value;
$("#pricedesc").text(range);
}
});
价格范围应为 0 至 2,000,000 美元。当我在滑块上滑动手柄时，虽然我得到了不寻常的值，例如“690 到 13”。双手柄滑块的工作原理是什么？
要访问双柄滑块中的滑块句柄值，您需要从滑块（“值”，索引）函数访问它们。试试下面的代码：
$(document).ready(function(){
$("#price").slider(
{ range: true,
min: 0,
max: 2000000,
change: function(e,ui) {
alert($("#price").slider("value", 0) + ' - ' + $("#price").slider("value", 1) );
}});
$("#price").slider("moveTo", 500000, 1);
});
<script type="text/javascript">
var str;
$(function() {
$("#slider-range").slider({
range: true,
min: 250,
max: 2500,
values: [500, 1000],
slide: function(event, ui) {
$("#amount").val('Rs' + ui.values[0] + ' - Rs' + ui.values[1]);
}
});
$("#amount").val('Rs' + $("#slider-range").slider("values", 0) + ' - Rs' + $("#slider-range").slider("values", 1));
//document.getElementById('valueofslide').value = arrIntervals[ui.values[1]];
});
</script>

轻微修正。您需要为双滑块调用 slider('values', n) 而不是 slide('value', n) 。
另一个轻微的修正，而不是：
$("#price").slider("moveTo", 500000, 1);
尝试以下代码，以便能够将第二个滑块处理程序设置为最大值；
var max = $('#price').slider('option', 'max');
$("#price").slider( 'values' , 1 , max );
