我有一个带有 AutoPostback 的单选按钮列表。单击特定项目时,我想停止回发并显示一个窗口。
如果 autopostback=false,我可以停止传播并显示一个窗口,所以我唯一需要的是能够停止回发。
我试图阻止回发,但没有运气。因此:关于如何停止回发的任何想法?我尝试了 preventDefault()、e.stopImmediatePropagation()、e.stopPropagation() 并返回 false。
我的单选按钮列表:
<asp:RadioButtonList ID="rblShippingMethod" runat="server" AutoPostBack="True" AppendDataBoundItems="true" />
呈现如下:
<table id="ctl00_ctl00_plhBody_plhMain_rblShippingMethod" border="0">
<tr>
<td><input id="ctl00_ctl00_plhBody_plhMain_rblShippingMethod_0" type="radio" name="ctl00$ctl00$plhBody$plhMain$rblShippingMethod" value="1,1" onclick="javascript:setTimeout('__doPostBack(\'ctl00$ctl00$plhBody$plhMain$rblShippingMethod$0\',\'\')', 0)" /><label for="ctl00_ctl00_plhBody_plhMain_rblShippingMethod_0">text</label></td>
</tr><tr>
<td><input id="ctl00_ctl00_plhBody_plhMain_rblShippingMethod_1" type="radio" name="ctl00$ctl00$plhBody$plhMain$rblShippingMethod" value="1,2" onclick="javascript:setTimeout('__doPostBack(\'ctl00$ctl00$plhBody$plhMain$rblShippingMethod$1\',\'\')', 0)" /><label for="ctl00_ctl00_plhBody_plhMain_rblShippingMethod_1">text</label></td>
</tr><tr>
<td><input id="ctl00_ctl00_plhBody_plhMain_rblShippingMethod_2" type="radio" name="ctl00$ctl00$plhBody$plhMain$rblShippingMethod" value="1,3" /><label for="ctl00_ctl00_plhBody_plhMain_rblShippingMethod_2">text<br/> <span class="deliveryOption">text</label></td>
</tr><tr>
<td><input id="ctl00_ctl00_plhBody_plhMain_rblShippingMethod_3" type="radio" name="ctl00$ctl00$plhBody$plhMain$rblShippingMethod" value="2" onclick="javascript:setTimeout('__doPostBack(\'ctl00$ctl00$plhBody$plhMain$rblShippingMethod$3\',\'\')', 0)" /><label for="ctl00_ctl00_plhBody_plhMain_rblShippingMethod_3">text</label></td>
</tr>
我有以下 JavaScript / jQuery:
<script type="text/javascript">
$(document).ready(function () {
var id = $('input[value="1,3"]').attr('id');
var combined = '#' + id;
$(combined).click(function (e) {
e.preventDefault();
e.stopImmediatePropagation();
e.stopPropagation();
magicMethod('mylink');
alert('Confirming I am even called');
return false;
});
});
</script>
$(combined).click() 中的警报运行。
有任何想法吗?谢谢!:-)
编辑:这是我的最终代码:
<script type="text/javascript">
// hack to override the default postback of the form
var oldPostBack;
var abortPostback = false;
window.onload = function () {
oldPostBack = __doPostBack;
__doPostBack = function () {
if (!abortPostback)
{
oldPostBack();
}
};
};
$(document).ready(function () {
var id = $('input[value="1,3"]').attr('id');
var combined = '#' + id;
$(combined).click(function(e) {
abortPostback = true;
mymagicmethod('parameter');
});
});
</script>
