问题描述
我有以下用于删除用户的脚本.如果我确认要删除用户,则脚本可以工作,但是如果我选择取消,则脚本仍会处理ajax提交并删除用户.我以为通过设置一个空的else {}语句将充当不执行任何操作",但是显然我在那是错的.
I have the following script I use for deleting users. The script works if I confirm that I want to delete the user but if I choose to cancel, the script still processes the ajax submission and deletes the user. I thought by setting an empty else{} statement would act as "do nothing" but apparently I was wrong there.
$("#user_delete_submit").click(function(){
var dataString = $("#frm_user_delete").serialize();
if(confirm("This cannot be undone, are you sure?")){
$.ajax({
type: "POST",
url: "/admin/user_delete.php",
data: dataString,
dataType : "json"
})
.done(function (data) {
$("#user_delete_dialog").dialog({
autoOpen: false,
modal: true,
close: function(event, ui) { window.location.href = "/admin/user_list.php"; },
title: "Account Deletion",
resizable: false,
width: 500,
height: "auto"
});
$("#user_delete_dialog").html(data.message);
$("#user_delete_dialog").dialog("open");
});
return false; // required to block normal submit since you used ajax
}else{
}
});
推荐答案
在其他情况下返回false ,如下所示:
in else return false like this:
$("#user_delete_submit").click(function(){
var dataString = $("#frm_user_delete").serialize();
if(confirm("This cannot be undone, are you sure?")){
$.ajax({
type: "POST",
url: "/admin/user_delete.php",
data: dataString,
dataType : "json"
})
.done(function (data) {
$("#user_delete_dialog").dialog({
autoOpen: false,
modal: true,
close: function(event, ui) { window.location.href = "/admin/user_list.php"; },
title: "Account Deletion",
resizable: false,
width: 500,
height: "auto"
});
$("#user_delete_dialog").html(data.message);
$("#user_delete_dialog").dialog("open");
});
return false; // required to block normal submit since you used ajax
}else{
return false;
}
});
