无法获得完整的js文件

[GavinLi]

为什么我通过HTTPxmlRequest "GET"服务器上的一个js文件，得到的文件内容不完整呢（取responseText的值）？
js文件大小为6.62k，是不是get方法有大小限制啊？该如何解决呢？？？？？

[shenjf2000]

有可能，不过get方法是发送的字节数有限制而不是接受的，你先试试POST方法看看。

[shenjf2000]

不过我觉得是get方法的可能性较小，也许不是得到文件内容不完整，而是你的js页面有问题。你先直接用ie看看你输出的js内容，然后在应用页面alert(XMLHttpreuest.responseText)看看是否一致。

To shenjf2000(一路走来):
已经察看过啦，alert的内容和原文件的内容不一致。我就奇怪了，有个js文件大小为6.73k，都可以照样get得到完整内容，为什么我这个js文件不得呢，怪了。难道是我写法有问题嘛？
js文件内容如下如下，请大家试试：

调用的方法如下（因为涉及到太多的js对象，贴完就太多啦，请大家自己试试看看）：
function updateProduct(ID)
{
oBaseInfo.ID = ID;
oBaseInfo.file.loadJsFile("AdminProduct","AdminProduct.js",null); //这里请求js文件
if ( !this.oAdminProductForm)
this.oAdminProductForm = new AdminProductForm();//这里new js文件定义的对象

//this.oAdminProductForm.loadAdminProductFormUI();
//this.oAdminProductForm.iniProductControls();
//this.oAdminProductForm.getProductDetail();
}

[GavinLi]

//动态装载js文件对象
function JsFileHelper()
{
this.loadFile = loadFile;
this.loadJsFile = loadJsFile;//动态装载js文件函数
this.loadCssFile = loadCssFile;//动态装载css文件函数
}

function loadFile(fileName,path)
{
var xDoc = null;
var url ="Client/BLL/"+fileName;
var params = "";
var httpMethod = "GET";
var docType = "txt";

if ( path )
url = path+"/"+fileName;

var oRequest = new RequestHelper();
oRequest.sendRequest(url,params,httpMethod,docType,false,null);

xDoc = oRequest.getDoc();

return xDoc;
}

function loadJsFile(objectID,fileName,path)
{
var oHead = null;
var oScript= document.getElementById(objectID);
if ( !oScript )
{
oHead = document.getElementsByTagName('head')[0];
oScript = document.createElement('script');
oScript.id = objectID;
oScript.type = "text/javascript";
oScript.text = this.loadFile(fileName,path);
oHead.appendChild(oScript);
}

if ( objectID == "AdminProduct" )
{
alert(oScript.text);
}
}

function loadCssFile(objectID,fileName,path)
{
var oHead = null;
var oScript= document.getElementById(objectID);
if ( !oScript )
{
oHead = document.getElementsByTagName('head')[0];
oScript = document.createElement('link');
oScript.id = objectID;
oScript.type = "text/css";
oScript.rel = "stylesheet";
oScript.href = path+"/"+fileName;//this.loadFile(fileName,path);
oHead.appendChild(oScript);
}
}

检查返回数据的长度
alert(obj.responseText.length);

注意，返回的是文本！需要用eval使之生效

[shenjf2000]

你使用的RequestHelper对象是一个封装好的js对象，不知道是否这个里面出了问题，可能是它的getDoc不对，lz跟踪调试一下看看。因为你的XMLHTTPRequest对象及调用是封装在这个里面的，另外你使用的是同步调用，它这个对同步调用的处理可能有点问题。

[GavinLi]

To xuzuning(唠叨):
我是放在header对象下面，可以不用eval。

[GavinLi]

问题已经找到，是js文件有问题。谢谢大家^_^

[shenjf2000]

这个问题同是否eval无关，你alert出来的内容同js内容不一致说明ajax取得的数据就不对，就不用考虑后面的执行是否正确，缩小范围检查。xuzuning(唠叨)说的方法也是让你检查ajax取得的数据长度，因此你注意力就在这个方面，看看requestHelper对象中的getDoc方法是怎样实现的等等。
