我的gridview中有一个输入按钮。我正在使用jquery捕获按钮的单击事件,如下所示(后面正在尝试实现电子邮件的读取未读功能):
$('.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');
}
}
});
在上述事件之后的同一页面上的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,当我第一次点击按钮时它会正常运行,但是在第二次点击时,事件没有被调用,并且tr点击内部的功能被运行...
但是当我刷新页面并做同样的事情然后再次刷新时,按钮事件就会运行...
此外,当我注释掉ajax部分时,它很好......我似乎也找不到任何语法错误。

更改以下代码
$('.toggleBtn').click(function(e) {
以下
$("body").on("click", ".toggleBtn", function(e){
我认为这就是你所需要的。
这里我将事件添加到body
,因为我不知道您的HTML结构。您应该将.on
附加到datagridview或其父级,以便事件不必冒泡太多。

在每一行上追加事件并不是一个好主意,尤其是当行数太多时。它会使脚本太沉重。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
。

尝试以下
function pageLoad(sender, args) {
$('.toggleBtn').click(function(e) {...}
}
这应该有效。实际上在asp.net中,您应该在 pageLoad()函数中附加所有事件。
