jQuery 和多选

发布于 2024-09-14 19:53:15 字数 1442 浏览 5 评论 0原文

在我的页面上,我必须选择 $.post 函数加载的选项值。我有一个按钮可以将数据从一个选择“移动”到另一选择。该示例适用于新页面,但不适用于我的页面。单击后,选定的元素不会移动到其他选择。

问题是还有另一种方法可以做到这一点,或者我如何纠正我的页面以使其正常工作?

示例代码:

<div style="float:left; border:1px solid red;">
    <div style="background-color:red; color:white;" align="center">INFORMATIVE</div>
    <div id="prop_info" style="float:left;">
        <div style="border:1px solid red;">PROPOSTI</div>
        <div style="float:left"><select multiple id="sel_info_pro" name="sel_info_pro" class="sel"><option value="b">a</option><option>b</option></select></div>
        <div style="float:left;"><a href="#" id="add_info"> >> </a><br><a href="#" id="remove_info"> << </a></div>
    </div>  
    <div id="conf_info" style="float:left;">
        <div style="border:1px solid red;">CONFIGURATI</div>
        <select multiple id="sel_info_conf" name="sel_info_conf" class="sel"></select>
    </div>
</div>
$(document).ready(function(){
    $('#add_info').click(function() {
        return !$('#sel_info_pro option:selected').remove().appendTo('#sel_info_conf');
    });
    $('#remove_info').click(function() {
        return !$('#sel_info_conf option:selected').remove().appendTo('#sel_info_pro');
    });
});

On my page I have to select option values loaded by a $.post function. I have a button to "move" data from one select to the other. The example works in a new page but not in my page not. The elements selected do not move to the other select after the click.

The question is there is another way to do it or how can I correct my page for making it work?

Example code:

<div style="float:left; border:1px solid red;">
    <div style="background-color:red; color:white;" align="center">INFORMATIVE</div>
    <div id="prop_info" style="float:left;">
        <div style="border:1px solid red;">PROPOSTI</div>
        <div style="float:left"><select multiple id="sel_info_pro" name="sel_info_pro" class="sel"><option value="b">a</option><option>b</option></select></div>
        <div style="float:left;"><a href="#" id="add_info"> >> </a><br><a href="#" id="remove_info"> << </a></div>
    </div>  
    <div id="conf_info" style="float:left;">
        <div style="border:1px solid red;">CONFIGURATI</div>
        <select multiple id="sel_info_conf" name="sel_info_conf" class="sel"></select>
    </div>
</div>
$(document).ready(function(){
    $('#add_info').click(function() {
        return !$('#sel_info_pro option:selected').remove().appendTo('#sel_info_conf');
    });
    $('#remove_info').click(function() {
        return !$('#sel_info_conf option:selected').remove().appendTo('#sel_info_pro');
    });
});

一点指导可能会有所帮助。如果您执行以下操作:

alert($('#sel_info_pro option:selected').length);

那么无论您选择了多少个,您都会得到 0 所选

选项实际上是针对 jQuery 对象上的 val() 存储的:

alert($('#sel_info_pro option').val().length); //gives you the count of options selected
alert($('#sel_info_pro option').val()[0]); //gives you the value of the first option selected

因此,上述方法将不起作用。您可能必须遍历数组,将它们与列表中的每个项目进行比较才能将它们移动。

A bit guidance that might help. If you did the following:

alert($('#sel_info_pro option:selected').length);

Then you would get 0, regardless of how many you had selected

The selected options are actually stored against the val() on the jQuery object:

alert($('#sel_info_pro option').val().length); //gives you the count of options selected
alert($('#sel_info_pro option').val()[0]); //gives you the value of the first option selected

So, the approach above will not work. You may have to iterate through the array, comparing them to each item in the list to move them over.

我找到了我的工作解决方案:

$(document).ready(function(){
$('#add_info').click(function() {
    var foop = []; 
    $('#sel_info_pro option:selected').each(function(z, selected){ 
        foop[z] = $(selected).val(); 
        return !$('#sel_info_pro option:selected').val(foop[z]).remove().appendTo('#sel_info_conf'); 
    });
}); 
$('#remove_info').click(function() { 
    var foo = []; 
    $('#sel_info_conf option:selected').each(function(i, selected){ 
        foo[i] = $(selected).val(); 
        return !$('#sel_info_conf option:selected').val(foo[i]).remove().appendTo('#sel_info_pro'); 
    });
});

});

谢谢大家的帮助!

I found my working solution:

$(document).ready(function(){
$('#add_info').click(function() {
    var foop = []; 
    $('#sel_info_pro option:selected').each(function(z, selected){ 
        foop[z] = $(selected).val(); 
        return !$('#sel_info_pro option:selected').val(foop[z]).remove().appendTo('#sel_info_conf'); 
    });
}); 
$('#remove_info').click(function() { 
    var foo = []; 
    $('#sel_info_conf option:selected').each(function(i, selected){ 
        foo[i] = $(selected).val(); 
        return !$('#sel_info_conf option:selected').val(foo[i]).remove().appendTo('#sel_info_pro'); 
    });
});

});

thanks everybody for help!
