多个jQuery滑块附加到多个选择下拉菜单 [英] Multiple jQuery sliders attached to multiple select dropdowns
问题描述
我正在尝试使用以下代码将滑块附加到我的下拉菜单中.其中之一正在工作,但是我在处理滑块的多个功能时遇到了麻烦.这就是我所拥有的-
Hi I am trying to use the following code to attach sliders to my dropdowns. One of them is working but I am having trouble with handling multiple functions for the sliders. Here's what I have --
`
<script>
jQuery(function($) {
var select = $( ".comment-overall_r select" );
var slider = $( "<div id='slider'></div>" ).insertAfter( select ).slider({
min: 1,
max: 6,
range: "min",
value: select[ 0 ].selectedIndex + 1,
slide: function( event, ui ) {
select[ 0 ].selectedIndex = ui.value - 1;
}
});
$( ".comment-overall_r select" ).change(function() {
slider.slider( "value", this.selectedIndex + 1 );
});
});
</script>
<script>
jQuery(function($) {
var select2 = $( ".comment-overall_n_r select" );
var slider2 = $( "<div id='slider'></div>" ).insertAfter( select2 ).slider({
min: 1,
max: 6,
range: "min",
value: select2[ 0 ].selectedIndex + 1,
slide: function( event, ui ) {
select2[ 0 ].selectedIndex = ui.value - 1;
}
});
$( ".comment-overall_n_r select" ).change(function() {
slider2.slider( "value", this.selectedIndex + 1 );
});
});
</script>
` 另外,我在控制台中看到第二个脚本/功能的错误-
` Also I see this error in the console for the 2nd script/function --
未捕获的TypeError:无法读取未定义的属性'selectedIndex'
Uncaught TypeError: Cannot read property 'selectedIndex' of undefined
我需要对4个下拉菜单执行此操作.如何正确执行?

推荐答案
请查看修改后的代码.有一个简单的小姐.您正在为两个滑块分配相同的ID <div id='slider'></div>
.我只是给他们单独的id
及其现在的工作.
Please look at modified code. There was simple miss. You were assigning same id <div id='slider'></div>
to both slider. I just given separate id
to them and its working now.
jQuery(function($) {
var select = $( ".comment-overall_r select" );
var slider = $( "<div id='slider'></div>" ).insertAfter( select ).slider({
min: 1,
max: 6,
range: "min",
value: select[ 0 ].selectedIndex + 1,
slide: function( event, ui ) {
select[ 0 ].selectedIndex = ui.value - 1;
}
});
$( ".comment-overall_r select" ).change(function() {
slider.slider( "value", this.selectedIndex + 1 );
});
var select2 = $( ".comment-overall_n_r select" );
var slider2 = $( "<div id='slider2'></div>" ).insertAfter( select2 ).slider({
min: 1,
max: 6,
range: "min",
value: select2[ 0 ].selectedIndex + 1,
slide: function( event, ui ) {
select2[ 0 ].selectedIndex = ui.value - 1;
}
});
$( ".comment-overall_n_r select" ).change(function() {
slider2.slider( "value", this.selectedIndex + 1 );
});
});
.mydiv{
margin-bottom: 30px;
}
select{
margin-bottom: 15px;
}
