[英]ASP.NET WebForms - How to suppress click actions on TreeView with JQuery?
我有以下代码:
<asp:Content ID="StyleContent" ContentPlaceHolderID="StyleContent" runat="server">
<style type="text/css">
#mask
{
position:absolute;
left:0;
top:0;
z-index:9000;
background-color:grey;
display:none;
}
#boxes .window
{
position:absolute;
left:0;
top:0;
width:440px;
height:200px;
display:none;
z-index:9999;
padding:20px;
}
#boxes #modalwindow
{
width:800px;
height:330px;
padding:10px;
background-color:#b9d3ee;
border: solid 2px #648abd
}
#boxes2 .window
{
position:absolute;
left:0;
top:0;
width:440px;
height:200px;
display:none;
z-index:9999;
padding:20px;
}
#boxes2 #modalwindowMoveCompany
{
width:350px;
height:800px;
padding:10px;
background-color:#ffffff;
border: solid 2px #648abd
}
.stylecenter
{
text-align: center;
}
</style>
</asp:Content>
<asp:Content ID="ScriptContent" ContentPlaceHolderID="ScriptContent" runat="server">
<script type="text/javascript">
$(document).ready(function () {
// Set up for displaying modal dialogs
$('a[name=modal]').click(function (e) {
// Prevent the default link behavior of navigation so we can use the link to show the Window
e.preventDefault();
// Determine which href was clicked if it was in fact an href (though this demo as only one.)
var id = $(this).attr('href');
// Determine browser windows dimensions.
var maskHeight = $(document).height();
var maskWidth = $(window).width();
// Set dimensions for the mask to opaque the screen when the modal window is displayed.
$('#mask').css({ 'width': maskWidth, 'height': maskHeight });
// Make the Window Opaque
$('#mask').fadeIn("fast");
$('#mask').fadeTo("slow", 0.8);
//Get the window height and width
var winH = $(window).height();
var winW = $(window).width();
// Set the Modal Window's dimensions to center in the browser window.
$(id).css('top', winH / 2 - $(id).height() / 2);
$(id).css('left', winW / 2 - $(id).width() / 2);
// Show the Modal Window
$(id).fadeIn("fast");
});
// // Suppress the node click in the CompanyTreeTarget control
// $('.IgnoreClicksInHere').click(function (e) {
// // Cancel the link behavior
// e.preventDefault();
// }
// Handle Close Button Click Event
$('.window .close').click(function (e) {
// Cancel the link behavior
e.preventDefault();
$('#mask').hide();
$('.window').hide();
});
// The user clicks OUTSIDE the Modal Window and the window will be closed without save.
$('#mask').click(function () {
$(this).hide();
$('.window').hide();
});
});
</script>
</asp:Content>
<asp:Content ID="MainContent" ContentPlaceHolderID="MainContent" runat="server">
...
<div id="boxes2">
<div id="modalwindowMoveCompany" class="window">
<center>Select company to be the new parent</center>
<div id="IgnoreClicksInHere" class="PrettyTree">
<uc1:CompanyTree ID="CompanyTreeTarget" runat="server" />
</div>
<asp:Button ID="SaveMoveCompany" runat="server" Text="Execute" onclick="SaveMoveCompany_Click" /> * To cancel just click on the grey area outside this dialog box.
</div>
<!-- Mask to cover the whole screen -->
<div id="Div3"></div>
</div>
<div id="boxes">
<div id="modalwindow" class="window">
<%--<center>Enter New User</center>--%><br />
<riv:UserDialog ID="UserDialog" runat="server" />
<%--<asp:Button ID="btnCancel" runat="server" OnClick="btnCancel_Click" Text="Cancel" Width="100px" />--%>
<%--<asp:Button ID="btnCreate" runat="server" OnClick="btnCreate_Click" Text="Create" Width="100px" />--%>
<asp:Button ID="ModalButton" runat="server" Text="Save User" onclick="ModalButton_Click" /> * To cancel just click on the grey area outside this dialog box.

</div>
</asp:Content>
现在,到目前为止一切工作都很好- 直到我在模式弹出窗口中单击树中的一个节点为止 。 然后退出弹出窗口,但我不希望它弹出。 我不擅长JQuery(上面的JQuery不是我的),并且我尝试使用上面注释掉的代码抑制节点click事件,但这样做是抑制了整个弹出窗口的显示!
关于如何抑制节点点击触发模式弹出窗口的JQuery关闭例程的任何想法?
TIA
我不确定代码为什么阻止对话框触发,但是您使用了类选择器而不是ID选择器。 您可能还需要阻止该事件的传播。
//
// Suppress the node click in the CompanyTreeTarget control
$('#IgnoreClicksInHere').click(function (e) {
return false; // prevents default action (on div?) and stops propagation up
});
通常,您可以从元素的click事件返回false,以防止浏览器对其进行处理。
$('node').click(function() { return false; });
