Javascript TypeError: xxx is not a function
提问by shashwat
Friends I came to a bit of problem. Everything was working fine before. But I can't rectify why it starts giving me such error.
Here is my JavaScript Code:
朋友我来有点问题。之前一切正常。但我无法纠正为什么它开始给我这样的错误。
这是我的 JavaScript 代码：
function newSupplier() {
$('div#AddSupplier div.msg').html('').hide();
$('div#AddSupplier div.loader').show();
registerSupplier($('div#AddSupplier table.frm :input').serialize()).done(function (a) {
if (a.Msg) {
$('div#AddSupplier div.msg').html(a.Msg).removeClass('success').addClass('error').fadeIn();
}
else if (a.supid) {
$('div#AddSupplier div.msg').html('Supplier <span class="l2">' + a.supid + '</span> Registered').removeClass('error').addClass('success').fadeIn();
$('div#AddSupplier table.frm :input').val('');
}
}).always(function () {
$('div#AddSupplier div.loader').hide();
}).fail(function () {
$('div#AddSupplier div.msg').html(errMsgNet).removeClass('success').addClass('error').fadeIn();
});
}
And here is the code of registerSupplier()function:
这是registerSupplier()函数的代码：
function registerSupplier(dataToPost) {
return $.ajax({
type: "POST",
url: jsonpath + 'Json.ashx?method=RegisterSupplier',
data: dataToPost
});
}
And here is the complete JS file: http://preview.myignou.com/Docs/jScript.js

If I am calling this function directly from FF and Firebug console then It is getting called.
But on button click I am getting error TypeError: newSupplier is not a function
如果我直接从 FF 和 Firebug 控制台调用这个函数，那么它就会被调用。
但是单击按钮时出现错误TypeError: newSupplier is not a function
Please ask me If u need additional code.
请问我是否需要额外的代码。
回答by
the first select tag in your html code has ID newSupplierjust like the name of the function. some browsers can access the node elements just by specifying the ID in the js code and then the function defined is overridden by the element in the DOM.
html 代码中的第一个 select 标签的 ID newSupplier就像函数的名称一样。一些浏览器可以通过在js代码中指定ID来访问节点元素，然后定义的函数被DOM中的元素覆盖。
you need to rename the function name or the element ID.
您需要重命名函数名称或元素 ID。
