问题描述

我的jquery代码有问题。我想使用jquery进行级联下拉列表。以下是我的代码。



HTML

 < SELECT class =input_stylename =comp_ddid =comp_dd> 
< option value =0> [Select]< / option>
< OPTION value =1> Company1< / OPTION>
< OPTION value =2> Company2< / OPTION>
< OPTION value =3> Company3< / OPTION>
< OPTION value =4> Company4< / OPTION>
< / SELECT>

< SELECT class =input_stylename =group_ddid =group_dd>
< option data-parent = - 1value =0> [Select]< / option>
< OPTION data-parent =1,3; value =1> grp_f< / OPTION>
< OPTION data-parent =1,2; value =2> grp_e< / OPTION>
< OPTION data-parent =1,3,4; value =3> grp_t< / OPTION>
< / SELECT>

jquery code

  $()。ready(function(){

$('#comp_dd')。change(function(){
var parent = $(this).val();
if(parent!= 0)
{
$('#group_dd')。children()。each(function(){
var listOfNumbers = $(this).data('parent');
if($(this).data('parent')!=' - 1')
{

var numbers = listOfNumbers.split(',');
if(jQuery.inArray(parent,numbers)!= - 1)
{
$(this).show ();
}
其他
{

$(this).hide();

}
}
});
}
其他
{
$('#group_dd')。children()。each(function(){
$(this ).show();
});
}
});
});

代码正常运行到 chrome和FF 但是无法使用 IE7 & IE8 .hide()无效 IE7和IE8

答案:(由Paulo Rodrigues提供)



js代码:

  var original = $('#group_dd')。clone(); 

$('#comp_dd')。change(function(){
var parent = $(this).val();

$('# group_dd')。empty()。append($(original).html());

if(parent!= 0){
$('#group_dd')。children( ).each(function(){
var listOfNumbers = $(this).data('parent');
if($(this).data('parent')!=' - 1' ){
var numbers = listOfNumbers.split(',');

if(jQuery.inArray(parent,numbers)== - 1){
$(this) .remove();
}
}
});
}
});


解决方案

.hide()会将样式显示更改为无,和IE不允许这样。所以我建议你删除这个元素。


I have a problem in my jquery code. I want to make a cascading dropdown using jquery. Below is my code for it.

HTML

<SELECT class="input_style" name="comp_dd" id="comp_dd">
    <option value="0">[Select]</option>
    <OPTION value="1">Company1</OPTION> 
    <OPTION value="2">Company2</OPTION> 
    <OPTION value="3">Company3</OPTION> 
    <OPTION value="4">Company4</OPTION> 
</SELECT>

<SELECT class="input_style" name="group_dd" id="group_dd">
    <option data-parent="-1" value="0">[Select]</option>
    <OPTION  data-parent="1,3"; value="1" >grp_f</OPTION> 
    <OPTION  data-parent="1,2"; value="2" >grp_e</OPTION> 
    <OPTION  data-parent="1,3,4"; value="3" >grp_t</OPTION> 
</SELECT>

jquery code

$().ready(function() {  

    $('#comp_dd').change(function() {
       var parent = $(this).val();
      if(parent!=0)
      {
       $('#group_dd').children().each(function() {
         var listOfNumbers = $(this).data('parent');        
        if($(this).data('parent')!='-1')
        {   

             var numbers = listOfNumbers.split(',');            
             if(jQuery.inArray(parent, numbers)!=-1 )
             {               
                  $(this).show();
            }
            else
            {               

                 $(this).hide();

            }
        }       
       });
      }
      else
      {
        $('#group_dd').children().each(function() {
             $(this).show();
       });
      }
    });
});

code works correctly into chrome and FF but not working in IE7 & IE8. .hide() is not working in IE7 and IE8

Please help me to get rid of it.

Thanks in advance

ANSWER:(given by Paulo Rodrigues)

js code:

var original = $('#group_dd').clone();

$('#comp_dd').change(function() {
    var parent = $(this).val();

    $('#group_dd').empty().append($(original).html());

    if (parent != 0) {
        $('#group_dd').children().each(function() {
            var listOfNumbers = $(this).data('parent');        
            if ($(this).data('parent')!='-1') {
                var numbers = listOfNumbers.split(',');

                if (jQuery.inArray(parent, numbers)==-1 ) {
                    $(this).remove();
                }
            }
       });
    }
});
解决方案

.hide() will change style display to none, and IE not allow this. So I recommend you remove this element.
