我对此很陌生
我有这个链接:
<a onclick = sendRequest('GET','room_chart.jsp') href=#>Show Chart</a>
但我需要在该链接内生成动态地址。
我创建了javascript:
<script language="javascript">
var selectedOption;
var ROOM;
var BUILDING;
function GetLink(){
selectedOption = document.getElementById("roomandbuildingid").options[e.selectedIndex].text; //getting selected option
ROOM = selectedOption.split("|")[0].trim().split(":")[1].trim(); //parsing text
BUILDING = selectedOption.split("|")[1].trim().split(":")[1].trim(); //parsing text
return "'room_chart.jsp?room="+ROOM+"&building="+ BUILDING+"'"; //returning url
}
</script>
但是当我将函数粘贴到其中时 - 它不起作用!
<a onclick = sendRequest('GET',GetLink()) href=#>Show Chart</a>
现在,经过调试,我发现它实际上创建了正确的 srting,但不知何故我的函数不愿意接受它作为 URL!这是一个悖论——它创建了正确的字符串——如果我将它硬编码到代码中——它就可以工作!但是来自变量的动态链接 - 不起作用!
请帮忙!
见下文:我的js文件:
function createRequestObject(){
var req;
if(window.XMLHttpRequest){
//For Firefox, Safari, Opera
req = new XMLHttpRequest();
}
else if(window.ActiveXObject){
//For IE 5+
req = new ActiveXObject("Microsoft.XMLHTTP");
}
else{
//Error for an old browser
alert('Your browser is not IE 5 or higher, or Firefox or Safari or Opera');
}
return req;
}
//Make the XMLHttpRequest Object
var http = createRequestObject();
function sendRequest(method, url){
if(method == "get" || method == "GET"){
http.open(method,url);
http.onreadystatechange = handleResponse;
http.send(null);
// alert( document.URL );
// document.write (GetLink());
}
}
function handleResponse(){
if(http.readyState == 4 && http.status == 200){
var response = http.responseText;
if(response){
document.getElementById("ajax_res").innerHTML = response;
}
}
}
