从 ascx 调用 jquery 函数不起作用
我遇到以下情况的问题。
我有一个 ascx,其中包含一个搜索条件的提交按钮,我试图在整个网站中使用的 js 文件中调用验证函数(这是我第一次在 ascx 中使用它)。
现在我刚刚尝试了这个:
<script type="text/javascript" src="js/jquery-1.3.2.js"></script>
<script type="text/javascript" src="js/jsAdmin_Generic_SystemValidation.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$(".submitBtn").click(function (e) {
alert("test");
alert($.Validate());
alert("test 2");
});
});
</script>
该文件被正确引用,因为我已经在 Firebug 中看到了由它完成的帖子。
这是函数:
jQuery.extend({
Validate: function () {
var requiredElements = $('.required').length; // Get the number of elements with class required
$('.required').each(function () {
// If value of textbox is empty and have not
// yet been validated then validate all required
// elements. i.e.
if (($(this).val() == "") || ($(this).hasClass("validationError")) || ($(this).hasClass("validationAlert")) || ($(this).hasClass("validationOk") == false)) {
validate($(this));
}
});
if ($('.validationOk').length == requiredElements) {
return true;
} else {
return false;
}
},
// Another extended function, this function
// is used for pages with the edit-in-place
// feature implemented.
validateElement: function (obj) {
var elementId = obj.attr("id"); // id of the button clicked.
var flag = 0;
if (elementId.toLowerCase() == "paymentmethodid") {
// Case elementId = paymentMethodId then check all the
// elements with css class starting with openStorage
var requiredElements = $(document).find("input[class*='openStorage']").length; // Get the number of elements with css class starting with openStorage
// Loop through all the elements with css class containing
// openStorage abd validate each element.
$(document).find("input[class*='openStorage']").each(function () {
if (($(this).val() == "") || ($(this).hasClass("validationError")) || ($(this).hasClass("validationAlert"))) {
validate($(this));
}
if ($(this).hasClass("validationOk")) {
flag++;
} else if (($(this).hasClass("validationError")) || ($(this).hasClass("validationAlert"))) {
flag--;
}
});
// If all elements are valid return true else return false
if (flag == requiredElements) {
return true;
} else {
return false;
}
} else if (elementId.toLowerCase() == "registeredfortax") {
if (($('.TaxRegistrationNumber').val() == "") || ($('.TaxRegistrationNumber').hasClass("validationError")) || ($('.TaxRegistrationNumber').hasClass("validationAlert"))) {
validate($('.TaxRegistrationNumber'));
}
if ($('.TaxRegistrationNumber').hasClass("validationOk")) {
return true;
} else {
return false;
}
} else {
var elementClass = "." + elementId;
if (($(elementClass).val() == "") || ($(elementClass).hasClass("validationError")) || ($(elementClass).hasClass("validationAlert")) || ($(elementClass).hasClass("validationOk") == false)) {
validate($(elementClass));
}
if ($(elementClass).hasClass("validationOk") && ($(elementClass).hasClass("required"))) {
return true;
} else if ($(elementClass).hasClass("required") == false) {
return true;
}else {
return false;
}
}
}
});
现在,我首先在 firebug 中得到“Validate() 不是函数”。自从我进行了警报测试以来,我收到了第一个警报,然后没有任何错误。
任何人都可以透露一些信息吗?
谢谢
I'm having a problem with the following situation.
I have an ascx which contains a submit button for a search criteria and I am trying to call a validation function in a js file I've used throughout the site (this is the first time I'm using it in an ascx).
Now I've just tried this:
<script type="text/javascript" src="js/jquery-1.3.2.js"></script>
<script type="text/javascript" src="js/jsAdmin_Generic_SystemValidation.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$(".submitBtn").click(function (e) {
alert("test");
alert($.Validate());
alert("test 2");
});
});
</script>
The file is being referenced correctly as I am already seeing posts in Firebug that are done by it.
This is the function:
jQuery.extend({
Validate: function () {
var requiredElements = $('.required').length; // Get the number of elements with class required
$('.required').each(function () {
// If value of textbox is empty and have not
// yet been validated then validate all required
// elements. i.e.
if (($(this).val() == "") || ($(this).hasClass("validationError")) || ($(this).hasClass("validationAlert")) || ($(this).hasClass("validationOk") == false)) {
validate($(this));
}
});
if ($('.validationOk').length == requiredElements) {
return true;
} else {
return false;
}
},
// Another extended function, this function
// is used for pages with the edit-in-place
// feature implemented.
validateElement: function (obj) {
var elementId = obj.attr("id"); // id of the button clicked.
var flag = 0;
if (elementId.toLowerCase() == "paymentmethodid") {
// Case elementId = paymentMethodId then check all the
// elements with css class starting with openStorage
var requiredElements = $(document).find("input[class*='openStorage']").length; // Get the number of elements with css class starting with openStorage
// Loop through all the elements with css class containing
// openStorage abd validate each element.
$(document).find("input[class*='openStorage']").each(function () {
if (($(this).val() == "") || ($(this).hasClass("validationError")) || ($(this).hasClass("validationAlert"))) {
validate($(this));
}
if ($(this).hasClass("validationOk")) {
flag++;
} else if (($(this).hasClass("validationError")) || ($(this).hasClass("validationAlert"))) {
flag--;
}
});
// If all elements are valid return true else return false
if (flag == requiredElements) {
return true;
} else {
return false;
}
} else if (elementId.toLowerCase() == "registeredfortax") {
if (($('.TaxRegistrationNumber').val() == "") || ($('.TaxRegistrationNumber').hasClass("validationError")) || ($('.TaxRegistrationNumber').hasClass("validationAlert"))) {
validate($('.TaxRegistrationNumber'));
}
if ($('.TaxRegistrationNumber').hasClass("validationOk")) {
return true;
} else {
return false;
}
} else {
var elementClass = "." + elementId;
if (($(elementClass).val() == "") || ($(elementClass).hasClass("validationError")) || ($(elementClass).hasClass("validationAlert")) || ($(elementClass).hasClass("validationOk") == false)) {
validate($(elementClass));
}
if ($(elementClass).hasClass("validationOk") && ($(elementClass).hasClass("required"))) {
return true;
} else if ($(elementClass).hasClass("required") == false) {
return true;
}else {
return false;
}
}
}
});
Now at first I was getting "Validate() is not a function" in firebug. Since I did that alert testing, I am getting the first alert, then nothing with no errors.
Can anyone shed some light?
Thanks
