而下面的脚本中的信息，请阅读以下信息。

var xmlhttp; 
function loadXMLDoc(url,cfunc){ 
    if (window.XMLHttpRequest) 
     {// code for IE7+, Firefox, Chrome, Opera, Safari 
     xmlhttp=new XMLHttpRequest(); 
     } 
    else 
     {// code for IE6, IE5 
     xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); 
     } 
    xmlhttp.onreadystatechange=cfunc; 
    xmlhttp.open("GET",url,true); 
    xmlhttp.send(); 
} 


function myFunction(){ 
    loadXMLDoc("subsysteminformation.txt",handleXML); 
} 
var checkState = function(xmlhttp, callback) { 
    if (xmlhttp.readyState == 4 && xmlhttp.status == 200) { 
    callback(); 
    } else { 
    // Check back again 1 sec later 
    setTimeout(checkState, 1000); 
    } 
}; 


function handleXML() 
    { 
checkState(xmlhttp, function() { 
    var txt=xmlhttp.responseText; 
    var datasets = []; 
    var datasetsCounter =0; 
    var secondPos; 
    var aPosition; 
    var currentCharacterLocation; 
while(txt.indexOf("#") > -1){ 
    aPosition = txt.indexOf("#"); 
    secondPos = txt.indexOf("#", (aPosition)+1); 
    aPosition++; 
    datasets[datasetsCounter]=txt.substring(aPosition, secondPos); 
    //var stringToCompare = txt.substring(aPosition, secondPos); 
    txt = txt.substring(secondPos); 
    datasetsCounter++; 
    document.write("done");

}

}); 
    } 
</script> 
</head> 
<body onLoad="myFunction()"> 
</body> 
</html>

现在我的问题

这部分是极其错误的

而（txt.indexOf（ “＃”）> - 1）{
aPosition = txt.indexOf（“＃”）; secondPos = txt.indexOf（“＃”，（aPosition）+1）; aPosition ++; 数据集[datasetsCounter] = txt.substring（aPosition，secondPos）; // var stringToCompare = txt.substring（aPosition，secondPos）; txt = txt.substring（secondPos）; datasetsCounter ++; document.write（“done”）; }

我想要做的是检查文本文件中是否有更多的“＃”字符，如果是这样读取所有内容（直到下一个“＃”字符或直到没有更多的字符在所有在文档中）到阵列数据集[我]，但我从来没有通过第一个＃，也许你们中有些聪明的人可以帮助我做我做错了什么，我应该写什么，而不是“如果txt.indexOf（“＃”）“来检查subsysteminformation.txt文件中是否还有”＃“字符？

另外，如果没有更多的”＃“符号，我该如何读取最后一位信息？字符在文字中？

谢谢事先=）

编辑I'ts一个加号，如果该sollution快，因为我会在文件subsysteminformation.txt大约100 “＃” 字符=）

EDIT 2的问题是，我从来没有走出“While”循环，它只是继续前进，我只是希望一旦使用了一个“＃”字符，就移动到下一个，不要重复使用相同的“＃” “性格再次。 =）

其他人如果不缩小范围，可能会将您的问题视为“过于本地化”，这样人们就可以知道提问的内容，主要问题是什么等等。我敢打赌，不需要这些代码的大部分，并且它的浏览时间太长。 – ninjagecko

@ninjagecko问题是，我从来没有离开“while”循环，它只是继续前进 – Adam

，你可以有这样的事情

var数据= xmlhttp.responseText.match（/^#(.[^;]*)/克）.MAP（函数（项目）{返回的eval（ “（” + item.replace（/ ^＃/， ''）+ “）”）}）

那么数据集将被评估对象的数组从文本文件

@TheBrain对不起，你可以请再次快速看一下这条线，它表示它期待另一个'） '，当我像这样添加它时 var datasets = xmlhttp.responseText.match（/^#(.[^#]*)/ gm）.map（function（item）{return eval（“（” + item.replace（/ ^＃/，''）+“）”}））; 它仍然抱怨（期待另一个'）'，我在做什么错了？我知道这是一个愚蠢的问题：P – Adam

是的，对不起var dataset = xmlhttp.responseText.match（/^#(.[^#]*)/ gm）.map（function（item）{return eval（“（” + item.replace（/ ^＃/，''）+“）”）}） – TheBrain

@Adam，您可能需要将match（）规则更改为/^#(.[^;]*)/否则，您会有eval（“（{name：value};）”），它会抛出一个错误。如果你读到的所有内容都是';'那么它应该工作得很好。 – TheBrain
