问题描述
我在做表单验证。在窗体检查功能中,我调用了一个ajax函数来验证字段。如果ajax的返回数据等于否,则此函数应返回false。但是,它从不等待ajax结果返回。我应该如何处理这个问题?
我的按钮代码:
I'm doing form validation. In the form check function, I called an ajax function to verify a field. if the return data of ajax equals "No", this function supposed to return false. However, it never wait for the ajax result return. How should I handle this issue?my button code:
jQuery代码:
function Checkform() {
var result = true;
$('input:password').each(function() {
if ($(this).val() == "") {
$(this).focus();
$(this).addClass('HighlightBorder');
alert("Please set password.");
result = false;
return false;
}
});
if (!result)
return false;
......
$.post(rootPath + "/AjaxPages/SearchAddress.aspx", { "street": street, "city": city, "state": state, "zip": zip, "type": "DPV" }, function(data) {
if (data == "No") {
alert("Invalid company address, did you type in a wrong address?");
result=false;
}
});
return result;
}
然后我将我的ajax代码修改为
Then I modified my ajax code to
$.post(rootPath + "/AjaxPages/SearchAddress.aspx", { "street": street, "city": city, "state": state, "zip": zip, "type": "DPV" }, function(data) {
if (data == "No") {
alert("Invalid company address, did you type in a wrong address?");
return false;
} else
return true;
$ b b
我认为这次返回值是在数据传出后执行的,但仍然不起作用。
I think this time the return value is performed after the data comes out, but still, it doesn't work.
推荐答案
ajax是异步的,因此您必须使用回调。
ajax is asynchronous, so you have to use callbacks.
$.post(rootPath + "/AjaxPages/SearchAddress.aspx", { "street": street, "city": city, "state": state, "zip": zip, "type": "DPV" }, function(data) {
if (data == "No") {
alert("Invalid company address, did you type in a wrong address?");
some_callback_function();//callback
}
});
