Uncaught TypeError: Cannot read property 'get' of undefined
提问by user3393001
Why am I getting this error, when I'm trying to get a response from a file on my own server?
当我尝试从我自己服务器上的文件中获取响应时，为什么会出现此错误？
$.get("http://www.example.com/user.php?q=" + client + "", function(response) {
if(response == "invalid"){
console.log("invalid login");
return;
}
And btw, the string client is mentioned already in the code.
顺便说一句，代码中已经提到了字符串客户端。
And jquery is included.
并且包括 jquery。

I have solve the problem like this ( i have jquery loaded async so i check if is defined and then get a css...etc..)
我已经解决了这样的问题（我已经异步加载了 jquery，所以我检查是否已定义，然后获取 css ......等等）
<script id="jquery" type='text/javascript' async defer src='//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js?ver=1.8.3'></script>
<script type='text/javascript'>
(function checkJQuery(){
if ('undefined' == typeof window.jQuery) {
setTimeout(function(){checkJQuery();},250);
}else{
var css = "url-of-my-css";
console.log("my css is loading");
window.jQuery.get( css, function( data ) {
$('<style>'+ data +'</style>').appendTo(document.getElementsByTagName('head')[0]);
console.log("css loaded");
});
var js = document.createElement('script');
js.type = 'text/javascript';
js.async = 'async';
js.defer = 'defer';
js.src = 'url-of-my-js';
var node = document.getElementsByTagName('script')[1];
node.parentNode.insertBefore(js, node);
}
})();
</script>
Changing $.get to window.JQuery.get
将 $.get 更改为 window.JQuery.get
Hope this help.
希望这有帮助。
