我在我的网格视图中有一个输入按钮。我正在使用jquery捕获按钮的点击事件,并在后面运行代码(基本上我是在尝试实现电子邮件的read-unread功能):
$('.toggleBtn').click(function(e) {
btnUnreadClicked = true;
$.ajax({
type: "POST",
url: "ClaimDetails.aspx/BtnOpenPDF",
data: "{'id': '" + letterid + "','anchText': '" + anchText + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
async: false,
success: function (msg) {
if (msg.d == 'Read') {
$tr.removeClass('unreadGridRow');
//update unread text to date time now
var d = new Date();
var replaceUnread = unreadColumn.toString().replace("Unread", d.format("dd/MM/yyyy"));
$tr.html(replaceUnread);
//update claim letter counts only
var parentRow = document.getElementById('__' + parentrowid).innerHTML;
var lblUnreadDocCount = $('#__' + parentrowid).find('#lblUnreadDocCount').text();
var finalCount = parseInt(lblUnreadDocCount) -1 ;
if(finalCount >= 0)
{
$('#__' + parentrowid).find('#lblUnreadDocCount').text(finalCount);
}
if(finalCount == 0 )
{
//remove the class
$('#__' + parentrowid).removeClass('unreadGridRow');
}
//get count of overall documents and subtract from it
var notification = $("#NewLetter3");
var numb = notification.text().match(/\d/g);
var finaldigits = numb.toString().replace(",", "");
var finalTotalDocsCount = parseInt(finaldigits) - 1;
if(finalTotalDocsCount >= 0)
{
//notification.text(notification.text().replace(numb, finalTotalDocsCount));
notification.html("You have " + finalTotalDocsCount + " unread Documents. Please click here to view");
//document.getElementById("NewLetter2").innerHTML = notification.text();
if(finalTotalDocsCount == 0)
{
$("#NewLetter2").hide();
}
}
$tr.find(".toggleBtn").text('Un-read');
}
else if (msg.d == 'Un-read') {
$tr.addClass('unreadGridRow');
//update unread text to date time now
var unreadDate = new Date();
var replaceRead = unreadColumn.toString().replace("Unread", unreadDate.format("dd/MM/yyyy"));
$tr.html(replaceRead);
//update claim letter counts only
var unreadparentRow = document.getElementById('__' + parentrowid).innerHTML;
var lblUnreadDocCountUnread = $('#__' + parentrowid).find('#lblUnreadDocCount').text();
var finalCountUnread = parseInt(lblUnreadDocCountUnread) + 1 ;
if(finalCountUnread >= 0)
{
$('#__' + parentrowid).find('#lblUnreadDocCount').text(finalCountUnread);
}
if(finalCountUnread > 0 )
{
//remove the class
$('#__' + parentrowid).addClass('unreadGridRow');
}
//get count of overall documents and subtract from it
var Unreadnotification = $("#NewLetter3");
if(Unreadnotification.text() == "" ) { Unreadnotification.html("You have 0 ");}
var Unreadnumb = Unreadnotification.text().match(/\d/g);
var Unreadfinaldigits = Unreadnumb.toString().replace(",", "");
var finalTotalDocsCountUnread = parseInt(Unreadfinaldigits) + 1;
if(finalTotalDocsCountUnread >= 0)
{
if(finalTotalDocsCountUnread >= 0)
{
$("#NewLetter2").show();
}
//notification.text(notification.text().replace(numb, finalTotalDocsCount));
Unreadnotification.html("You have " + finalTotalDocsCountUnread + " unread Documents. Please click here to view");
//document.getElementById("NewLetter2").innerHTML = notification.text();
}
$tr.find(".toggleBtn").text('Read');
}
}
});在上面的事件之后的同一页上,我有另一个捕获行点击的事件,如下所示:
$("#<%=gvClaimDtSentDate.ClientID%> tr:has(td)").click(function (e) {
if( $(this).closest('tr').hasClass('parent'))
{
if(btnUnreadClicked == false)
{
// do stuff related to row click
}
btnUnreadClicked = false;现在,当我第一次单击按钮时,它工作正常,事件会被调用,但在第二次单击时,事件不会被调用,tr click中的功能会运行……
但是,当我刷新页面并做同样的事情,然后再次刷新按钮事件运行...
另外,当我注释掉ajax部分时,它也很好……我似乎也找不到其中的任何语法错误。

更改以下代码
$('.toggleBtn').click(function(e) {添加到以下内容
$("body").on("click", ".toggleBtn", function(e){我想这就是你需要的。
这里我将事件添加到body,因为我不知道你的超文本标记语言的结构。您应该将.on附加到datagridview或其父视图,这样事件就不必冒泡太多。
更新:
在每一行上追加事件不是一个好主意,特别是当有太多行的时候。这会使脚本过于繁重。因此,建议在这些情况下使用.on。在旧版本的jQuery中,您可能必须使用.live而不是.on。

请尝试以下操作
function pageLoad(sender, args) {
$('.toggleBtn').click(function(e) {...}
}这应该是可行的。实际上,在asp.net中,您应该在pageLoad()函数中附加所有事件。
