而下面的腳本中的信息,請閱讀以下信息。
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>
現在我的問題
這部分是極其錯誤的
而(txt.indexOf( 「#」)> - 1){
aPosition = txt.indexOf(「#」); secondPos = txt.indexOf(「#」,(aPosition)+1); aPosition ++; 數據集[datasetsCounter] = txt.substring(aPosition,secondPos); // var stringToCompare = txt.substring(aPosition,secondPos); txt = txt.substring(secondPos); datasetsCounter ++; document.write(「done」); }
我想要做的是檢查文本文件中是否有更多的「#」字符,如果是這樣讀取所有內容(直到下一個「#」字符或直到沒有更多的字符在所有在文檔中)到陣列數據集[我],但我從來沒有通過第一個#,也許你們中有些聰明的人可以幫助我做我做錯了什麼,我應該寫什麼,而不是「如果txt.indexOf(「#」)「來檢查subsysteminformation.txt文件中是否還有」#「字符?
另外,如果沒有更多的」#「符號,我該如何讀取最後一位信息?字符在文字中?
謝謝事先=)
編輯I'ts一個加號,如果該sollution快,因爲我會在文件subsysteminformation.txt大約100 「#」 字符=)
EDIT 2的問題是,我從來沒有走出「While」循環,它只是繼續前進,我只是希望一旦使用了一個「#」字符,就移動到下一個,不要重複使用相同的「#」 「性格再次。 =)
其他人如果不縮小範圍,可能會將您的問題視爲「過於本地化」,這樣人們就可以知道提問的內容,主要問題是什麼等等。我敢打賭,不需要這些代碼的大部分,並且它的瀏覽時間太長。 – ninjagecko
@ninjagecko問題是,我從來沒有離開「while」循環,它只是繼續前進 – Adam
