我的网页上有这样的代码片段:
timeout = setTimeout(function() {highlight(transfer);}, 1500);
我需要用户可以使用下拉列表或复选框将1500值更改为其他值。谁可以帮助我?

试试这个
var timeout; //populate as required from dropdown/checkboxes
timeout = setTimeout(function() {highlight(transfer);}, timeout);

HTML:
<select id="selectInterval" onChange="setNewValue.call(this,event)">
<option value="">Select Interval</option>
<option value="1500">1,5 seconds</option>
<option value="2000">2 seconds</option>
<option value="2500">2,5 seconds</option>
</select>
JS:
var timeout;
setNewValue= function(e){
var _v = this.value;
if(typeof _v == "undefined" || _v == "") return;
timeout = setTimeout(function() {highlight(transfer);}, _v);
}
HTML:
<div class="dropdown">
<span class="evalued" rel="">Select Interval</span>
<ul class="options">
<li class="item" style="display:none"><a class="selected" rel="">Select Interval</a></li>
<li class="item"><a rel="1500">1,5 seconds</a></li>
<li class="item"><a rel="2000">2,0 seconds</a></li>
<li class="item"><a rel="2500">2,5 seconds</a></li>
</ul>

$(function(){
setNewValue2 = function(){

}
$(".dropdown a").on("click",function(e){
e.preventDefault();
var _r = $(this).attr("rel");
var _t = $(this).text();
$(this).parents(".options").find(".item").show();
$(this).parent().hide();
$(this).parents(".dropdown").find(".evalued").prop({
innerHTML : _t,

<!-- Our Dropdown -->
<select id="timeout">
<option>500</option>
<option>1000</option>
<option>1500</option>
</select>
<script>
var timeout; // we will keep selected value
$("#timeout").change(function(){
timeout=$(this).val();
timeout = setTimeout(function() {highlight(transfer);}, timeout);
});
</script>
