问题描述

我有asp.net项目,在那里我有一个母版页,我包括这一行,以引用JS文件

 < script type =text / javascriptsrc =Scripts / HideDIV.js>< / script> 

在JS文件中我有这个函数:

  function hideDiv(){
document.getElementById('div1')。style.display ='none';
document.getElementById('div2')。style.display ='none';
$ b $ if(document.getElementById('RadioButtonTipoUser_0')!= null){
if(document.getElementById('RadioButtonTipoUser_0')。checked){
document.getElementById(' div1')。style.display ='block'; (document.getElementById('RadioButtonTipoUser_1')!= null){
if(document.getElementById('RadioButtonTipoUser_1')。checked)



if {

document.getElementById('div2')。style.display ='block';




$ / code>

基本上我需要在这个RadioButtonList上调用Js的一个函数hideDiv(),当选择一个Button时,一个div隐藏传递给visible。



这段代码在内容。

 < div> 
< asp:RadioButtonList ID =RadioButtonTipoUserrunat =serverRepeatDirection =Horizo​​ntalonchange =hideDiv()>

< asp:ListItem Selected =trueValue =1> Dome< / asp:ListItem>
< asp:ListItem Value =2> Emp< / asp:ListItem>
< asp:ListItem Value =3> Vet< / asp:ListItem>
< / asp:RadioButtonList>


< / div>

< div id =div1style =display:none>
< a> Charls< / a>
< / div>
< div id =div2style =display:none>< a> Maris< / a>< / div>
< / div>

我做了一个调试,错误信息是


ReferenceError:hideDiv未定义


我如何使onchange =hideDiv() 调用HideDiv()函数?

解决方案

使用jquery完成您的任务

HTML

 < DIV> 
< asp:RadioButtonList ID =RadioButtonTipoUserrunat =serverRepeatDirection =Horizo​​ntal>

< asp:ListItem Selected =trueValue =1> Dome< / asp:ListItem>
< asp:ListItem Value =2> Emp< / asp:ListItem>
< asp:ListItem Value =3> Vet< / asp:ListItem>
< / asp:RadioButtonList>


< / div>

< div id =div1>
< a> Charls< / a>
< / div>
< div id =div2>< a> Maris< / a>< / div>

JQUERY
< $($#$)$($#$)$($#$)$($# ('(this).is(':checked(');
$('#RadioButtonTipoUser_1')。on('change',function(){

if ')){
$('#div1')。show();
$('#div2')。hide();
}
}); $ b ($(this).is(':checked'))$ b $('#RadioButtonTipoUser_2')on('change',function(){
alert(ok1);
{
$('#div1')。hide();
$('#div2')。show();
}
});
} );


i have asp.net project, where i have a master-page on I include this line, to reference of the JS file

<script type="text/javascript" src="Scripts/HideDIV.js"></script>

In the JS file i have this function:

function hideDiv() {
    document.getElementById('div1').style.display = 'none';
    document.getElementById('div2').style.display = 'none';

    if (document.getElementById('RadioButtonTipoUser_0') != null) {
        if (document.getElementById('RadioButtonTipoUser_0').checked) {
            document.getElementById('div1').style.display = 'block';
        }
    }

    if (document.getElementById('RadioButtonTipoUser_1') != null) {
        if (document.getElementById('RadioButtonTipoUser_1').checked) {

            document.getElementById('div2').style.display = 'block';

        }
    }
}

Basically i need on this RadioButtonList, call a function on Js "hideDiv()", when a select the one Button, one div hide pass to visible.

This code is in content.

<div>
        <asp:RadioButtonList ID="RadioButtonTipoUser" runat="server" RepeatDirection="Horizontal" onchange="hideDiv()">

            <asp:ListItem Selected="true" Value="1">Dome</asp:ListItem>
            <asp:ListItem Value="2">Emp</asp:ListItem>
            <asp:ListItem Value="3">Vet</asp:ListItem>
        </asp:RadioButtonList>


    </div>

    <div id="div1" style="display:none">
        <a>Charls</a>
    </div>
    <div id="div2" style="display:none"><a>Maris</a></div>
</div>

I make a debug and the error msg is

ReferenceError: hideDiv is not defined

how i make tho the onchange="hideDiv()" call the HideDiv() function?

解决方案

you use jquery for achieving your task

HTML

<div>
        <asp:RadioButtonList ID="RadioButtonTipoUser" runat="server" RepeatDirection="Horizontal">

            <asp:ListItem Selected="true" Value="1">Dome</asp:ListItem>
            <asp:ListItem Value="2">Emp</asp:ListItem>
            <asp:ListItem Value="3">Vet</asp:ListItem>
        </asp:RadioButtonList>


    </div>

    <div id="div1" >
        <a>Charls</a>
    </div>
    <div id="div2" ><a>Maris</a></div>

JQUERY

 $(document).ready(function () {

        $('#div1').hide();
        $('#div2').hide();
        $('#RadioButtonTipoUser_1').on('change', function () {

            if ($(this).is(':checked')) {
                $('#div1').show();
                $('#div2').hide();
            }
        });
        $('#RadioButtonTipoUser_2').on('change', function () {
            alert("ok1");
            if ($(this).is(':checked')) {
                $('#div1').hide();
                $('#div2').show();
            }
        });
    });
