此代码仅在我重新加载/刷新页面时有效，否则它不起作用，我认为问题是，因为我使用Jquery +普通的javascript。
我有表格并且有输入使用自动完成，但是当你接下来通过表格时，它不起作用。
关键是#SchoolName的输入不是第一页上的第二页（在showcart（）之后;函数是三角形的）......
任何人都有任何想法为什么我的jquery代码没有正确加载？
我有这段代码：
<script type="text/javascript" language="javascript">
function autocomplete() {
$("#SchoolName").autocomplete("ajaxFuncs.php", {
cacheLength:1,
mustMatch:1,
extraParams: {getSchoolName:1}
});
};
$(document).ready(function(){
setTimeout("autocomplete()", 500);
});
function showVal(str) {
if (str == "") {
document.getElementById("txtHint").innerHTML = "* Please type in School Name.";
return;
}
if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp = new XMLHttpRequest();
} else {// code for IE6, IE5
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange = function () {
if (xmlhttp.readyState == 4) {
if (xmlhttp.status == 200) { // break this into 2 statements so you can handle HTTP errors
document.getElementById("txtHint").innerHTML = xmlhttp.responseText;
} else {
document.getElementById("txtHint").innerHTML = "AJAX Error (HTTP "+xmlhttp.status+")";
}
}
}; // functions declared in this way should be followed by a semi colon, since the function declaration is actually a statement.
// encodeURIComponent() does all the escaping work for you - it is roughly analogous to PHP's urlencode()
// xmlhttp.open("GET","ajaxFuncs2.php?q="+encodeURIComponent(str),true);
xmlhttp.open("GET","ajaxFuncs2.php?q="+encodeURIComponent(str),true);
xmlhttp.send();
}

尝试移动最后一行：
setTimeout("showCart();", 100);
...进入$ .ready-function：
$(document).ready(function(){
setTimeout("autocomplete()", 500);
});
否则可能会发生showCart（）在您在showCart（）中访问的元素已知之前被调用。

首先：结合jQuery +常规javascript不是问题 - jquery是由常规的javascript组成的。
其次，当你将一个方法传递给你的回调参数时，你通常可以只写出方法的名称：
$(document).ready(function(){
setTimeout(autocomplete, 500);
});
第三，使用XMLHttpRequest同时也使用jquery的问题。 Jquery有一个XHR版本，它比那更符合跨浏览器标准，你应该使用它：
$.ajax()
最后，请在代码开头的实际jquery文件中添加一个include ..
<script type="text/javascript" src="jquery.js"></script>

很抱歉，在格式化代码时，真的很难做到。
我现在看到了一些问题： -
function autocomplete() {首先此功能使用分号};
//Send the proper header information along with the request doc.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); doc.setRequestHeader("Content-length", params.length); doc.setRequestHeader("Connection", "close"); document.body.style.cursor = "wait"; doc.send(params); document.body.style.cursor = "default";</li>
3.如果您使用的是JQuery，则不需要XMLHttpRequest
4.要更新......
