我正在加载一个下拉菜单,假设它下面加载内容。我把我的文件分解了。
问题: 在其中一个内容框中,我遇到了来自twitter和disqus小部件的Javascript问题。如果没有在AJAX中实现,一切正常。在AJAX中,所有内容都显示为空白,Firefox正在给我304 Not Modified。
AJAX代码
// AJAX Page Reload
var bustcachevar = 1 //bust potential caching of external pages after initial request? (1=yes, 0=no)
var loadedobjects = ""
var rootdomain = "http://" + window.location.hostname
var bustcacheparameter = ""
function ajaxpage(url, containerid) {
var page_request = false
if (window.XMLHttpRequest) // if Mozilla, Safari etc
page_request = new XMLHttpRequest()
else if (window.ActiveXObject) { // if IE
try {
page_request = new ActiveXObject("Msxml2.XMLHTTP")
} catch (e) {
try {
page_request = new ActiveXObject("Microsoft.XMLHTTP")
} catch (e) {}
}
} else return false
page_request.onreadystatechange = function () {
loadpage(page_request, containerid)
}
if (bustcachevar) //if bust caching of external page
bustcacheparameter = (url.indexOf("?") != -1) ? "&" + new Date().getTime() : "?" + new Date().getTime()
page_request.open('GET', url + bustcacheparameter, false)
page_request.send(null)
}
function loadpage(page_request, containerid) {
if (page_request.readyState == 4 && (page_request.status == 200 || window.location.href.indexOf("http") == -1)) document.getElementById(containerid).innerHTML = page_request.responseText
}
function loadobjs() {
if (!document.getElementById) return
for (i = 0; i < arguments.length; i++) {
var file = arguments[i]
var fileref = ""
if (loadedobjects.indexOf(file) == -1) { //Check to see if this object has not already been added to page before proceeding
if (file.indexOf(".js") != -1) { //If object is a js file
fileref = document.createElement('script')
fileref.setAttribute("type", "text/javascript");
fileref.setAttribute("src", file);
} else if (file.indexOf(".css") != -1) { //If object is a css file
fileref = document.createElement("link")
fileref.setAttribute("rel", "stylesheet");
fileref.setAttribute("type", "text/css");
fileref.setAttribute("href", file);
}
}
if (fileref != "") {
document.getElementsByTagName("head").item(0).appendChild(fileref)
loadedobjects += file + " " //Remember this object as being already added to page
}
}
}
/***Combo Menu Load Ajax snippet**/
function ajaxcombo(selectobjID, loadarea) {
var selectobj = document.getElementById ? document.getElementById(selectobjID) : ""
if (selectobj != "" && selectobj.options[selectobj.selectedIndex].value != "") ajaxpage(selectobj.options[selectobj.selectedIndex].value, loadarea)
}
位于头部的JavaScript代码
<script src="js/scripts.js" type="text/javascript"></script>
<script src="http://widgets.twimg.com/j/2/widget.js"></script>
<script type="text/javascript"> var disqus_developer = 1; </script>
<script src="//platform.twitter.com/widgets.js" type="text/javascript"></script>
下拉菜单代码位于Header.php
<form>
<select id="ajaxmenu" size="1" onChange="ajaxcombo('ajaxmenu', 'contentarea')">
<option value="issue/test1.php">test1</option>
<option value="issue/test2.php">test2</option>
<option value="issue/test3.php">test3</option>
</select>
</form>
Twitter小部件代码位于1.php
<script>
new TWTR.Widget({
version: 2,
type: 'search',
search: '#Discuss',
interval: 30000,
title: '',
subject: '',
width: 255,
height: 300,
theme: {
shell: {
background: 'transparent', //this is important
},
tweets: {
background: 'transparent', //this is important
color: '#444444',
links: '#1985b5'
}
},
features: {
scrollbar: false,
loop: true,
live: true,
behavior: 'all'
}
}).render().start();
</script>
次要问题: 当我从下拉菜单中选择一个部分并刷新页面时,下拉菜单会中断。我的意思是如果我在test1并选择test2,在加载新内容后,我刷新页面,下拉菜单将保留在test2上,但内容将在test1上。如果有人知道一个快速解决这个问题的方法,那就太棒了。
这是我第一次在这里发帖,所以如果我碰巧搞砸了,请告诉我。我试图提供尽可能多的信息,因为我一直在搜索关于如何解决这个问题的两天。
先谢谢。
