文件未在Javascript中使用OpenTextFile打开

在这里，我试图通过在html中选择包含txt文件名（如hello.txt）的列表框来打开该文件

我给出的路径如下E:\DragableExample\Documents\+selected

此处所选的值为hello.txt

function savedload()
{
var doc = new ActiveXObject("Scripting.FileSystemObject");
var dpt = document.getElementById("sltrtcnty");
var selected=  dpt.options[dpt.selectedIndex].value;
var txt = doc.OpenTextFile("E:\\DragableExample\\Documents\\"+selected,1,true);
alert(txt);
var row=txt.ReadAll();  
document.all.mySaveModel.value = row;
var str = document.getElementById("mySavedModel").value;
myDiagram.model = go.Model.fromJson(document.all.mySavedModel.value );
myDiagram.model.undoManager.isEnabled = true;
doc.quit(0);

}

使用jQuery.get读取文本文件

jQuery.get('file.txt', function(data) {
   alert(data);
   //process text file line by line
   $('#div').html(data.replace('n','<br />'));
});

首先，您可以使用alertselected variable have hello.txt检查所选变量的值。您是否在alert am getting simple hello.txt selected form listbox中收到任何错误消息在HTMLID中您在ReadAll后检查alertrow
