ajax 刷新错误

[vivihewitt]

我用PHP把javascript封成了一下这个类，但是当两个AjaxNode对象有包含关系的时候，内层那个不能正确的刷新，研究了一天了 不知道为什么

class AjaxNode extends NodeContainer {

	/**
	 * The container div
	 * @var PageElement
	 */
	public $containerDIV;

	/**
	 * The ID of the container DIV
	 * @var String
	 */
	public $containerID;

	/**
	 *
	 * @param <type> $parent
	 * @param <type> $ajaxURL
	 * @param <type> $ajaxOnLoad
	 */
	function __construct($parent, $ajaxURL = null, $ajaxOnLoad = true, $loadingText = null, $delayInterval = null, $autoRefresh = false) {
		parent::__construct($parent);

		new Script($this, "text/javascript", "/includes/htmlTree/classes/Element/AjaxNode.class.php?include=javascript");

		$this->containerID = md5(uniqid(mt_rand(), true));

		$this->containerDIV = new PageElement($this, "div", $loadingText);
		$this->containerDIV->setID($this->containerID);
		$this->containerDIV->addAttribute("ajaxurl", $ajaxURL);
		$this->containerDIV->forceEndTag();

		if($ajaxOnLoad){
			$autoLoadScript = new Script($this, "text/javascript");

			if($delayInterval == null){
				$autoLoadScript->contentText = $this->getTriggerJavacript();
			}
			else{
				if($autoRefresh){
					$autoLoadScript->contentText = "var ajaxNode" . $this->containerID . "Refresher = window.setInterval(\"". $this->getTriggerJavacript(). "\", $delayInterval);";
				}
				else{
					$autoLoadScript->contentText = "var ajaxNode" . $this->containerID . "Loader = window.setTimeout(\"". $this->getTriggerJavacript(). "\", $delayInterval);";
				}
			}
		}
	}

	public function getTriggerJavacript(){
		return "loadAJAXHTMLNodeContent('$this->containerID');";
	}
}

	function loadAJAXHTMLNodeContent(ajaxNodeID){
		var ajaxHTMLNodeRequester = null;

		try{
			// Firefox, Opera 8.0+, Safari
			ajaxHTMLNodeRequester = new XMLHttpRequest();
		}
		catch(e){
			// Internet Explorer
			try{
				ajaxHTMLNodeRequester = new ActiveXObject("Msxml2.XMLHTTP");
			}
			catch(e){
				ajaxHTMLNodeRequester = new ActiveXObject("Microsoft.XMLHTTP");
			}
		}

		var ajaxHTMLNodeURL = document.getElementById(ajaxNodeID).getAttribute('ajaxurl');


		ajaxHTMLNodeRequester.open('GET', ajaxHTMLNodeURL, true);
		ajaxHTMLNodeRequester.onreadystatechange = function(){
				if(ajaxHTMLNodeRequester.readyState == 4){
					if(ajaxHTMLNodeRequester.status == 200) {
						document.getElementById(ajaxNodeID).innerHTML = ajaxHTMLNodeRequester.responseText;
						var forcedXML = "<root>" + ajaxHTMLNodeRequester.responseText + "</root>";
						
						if(window.DOMParser){
							parser=new DOMParser();
							xmlDoc=parser.parseFromString(forcedXML,"text/xml");
							}
						else{
							// Internet Explorer
							xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
							xmlDoc.async="false";
							xmlDoc.loadXML(forcedXML); 
						}
						
						var scriptTags = xmlDoc.getElementsByTagName("script");
						var scriptTagCount = scriptTags.length;
						if(scriptTagCount > 0){
							var i = 0;

							for(i = 0; i < scriptTagCount; i++){
								if(scriptTags[i].getAttribute('src') == null || scriptTags[i].getAttribute('src') == ''){
									eval(scriptTags[i].childNodes[0].nodeValue);
								}
								else{
									var newScriptTag = document.createElement("script");
									newScriptTag.setAttribute("src", scriptTags[i].getAttribute('src'));
									document.getElementById(ajaxNodeID).appendChild(newScriptTag);
								}
							}
						}

						var linkTags = xmlDoc.getElementsByTagName("link");
						var linkTagsCount = linkTags.length;
						if(linkTagsCount > 0){
							var i = 0;

							for(i = 0; i < linkTagsCount; i++){
								if(linkTags[i].getAttribute('href') == null || linkTags[i].getAttribute('href') == ''){
									//donothing
								}
								else{
									var newLinkTag = document.createElement("link");
									newLinkTag.setAttribute("rel", linkTags[i].getAttribute('rel'));
									newLinkTag.setAttribute("href", linkTags[i].getAttribute('href'));
									document.getElementById(ajaxNodeID).appendChild(newLinkTag);
								}
							}
						}

						var styleTags = xmlDoc.getElementsByTagName("style");
						var styleTagsCount = styleTags.length;
						if(styleTagsCount > 0){
							var i = 0;

							for(i = 0; i < styleTagsCount; i++){
								var newSyleTag = document.createElement("style");
								var styleCode = document.createTextNode(styleTags[i].childNodes[0].nodeValue);
								newSyleTag.type = "text/css";
								if(newSyleTag.styleSheet){
									newSyleTag.styleSheet.cssText = styleCode.nodeValue;
								}
								else{
									newSyleTag.appendChild(styleCode);
								}
								
								document.getElementById(ajaxNodeID).appendChild(newSyleTag);
							}
						}
					}
					else{
						document.getElementById(ajaxNodeID).innerHTML = "Error code " + ajaxHTMLNodeRequester.status + " in loadAJAXHTMLNodeContent('" + ajaxNodeID + "'')";
					}
				}
			};

		ajaxHTMLNodeRequester.send(null);

贴出你php返回的xml字符串，如果是js去不到xml中的值的话可以帮你解决下

如果是你php关系没整理好，没返回正确的xml什么的这个就帮补到了，木知道这么深的php。。。

应该是逻辑问题，建议移到php版块·

建议用jQuery的Ajax，相当方便！
