通过ajax连接在同一台计算机上使用服务器和客户端时,它显示服务器的非活动状态。在使用动态脚本标记时,它不反映服务器的不活动性。怎么能解决这个问题?
我们已将这些功能包含在.js文件中。
function JSONscriptRequest(fullUrl) {
this.fullUrl = fullUrl;
this.noCacheIE = '&noCacheIE=' + (new Date()).getTime();
this.headLoc = document.getElementsByTagName("head").item(0);
this.scriptId = 'JscriptId' + JSONscriptRequest.scriptCounter++;
}
JSONscriptRequest.scriptCounter = 1;
JSONscriptRequest.prototype.buildScriptTag = function () {
this.scriptObj = document.createElement("script");
this.scriptObj.setAttribute("type", "text/javascript");
this.scriptObj.setAttribute("charset", "utf-8");
this.scriptObj.setAttribute("src", this.fullUrl + this.noCacheIE);
this.scriptObj.setAttribute("id", this.scriptId);
}
JSONscriptRequest.prototype.removeScriptTag = function () {
this.headLoc.removeChild(this.scriptObj);
}
JSONscriptRequest.prototype.addScriptTag = function () {
this.headLoc.appendChild(this.scriptObj);
}
并在jsp页面中使用以下代码
// The web service call
var req = <<<url of the service which resides in different server>>>&callback=<callback function>;
// Create a new request object
bObj = new JSONscriptRequest(req);
// Build the dynamic script tag
bObj.buildScriptTag();
// Add the script tag to the page
bObj.addScriptTag();
