JavaScript的使用的setTimeout（）与循环 [英] javascript using settimeout() with a loop

问题描述

香港专业教育学院有一个表，8x10的细胞..每卖出了输入的元素有自己的ID（11，12，...，21,22,23，......）
现在我想后和填补这些输入（可以说0.5秒）
我刚刚进入一些值测试

ive got a table with 8x10 cells.. each sell got an input element with its own id (11, 12, ... , 21,22,23,...) now i want to fill these inputs after and after (lets say 0.5 sec) i just entered some values for testing

        Betrag = new Array();
        Betrag[0] = new Array();
        Betrag[1] = new Array("asd","asd","asd","asd","asd","asd","asd","asd","asd","asd","513.000,00");
        Betrag[2] = new Array("asd","adsd","asd","asd","asd","asd","asd","asd","asd","asd","asd");
        Betrag[3] = new Array("asd","asd","asd","asd","asd","asd","asd","asd","asd","asd","asd");
        Betrag[4] = new Array("asd","uisgui","asd","asd","asd","asd","asd","asd","asd","asd","asd");
        Betrag[5] = new Array("asd","asd","asd","asd","asd","asd","asd","asd","asd","asd","asd");
        Betrag[6] = new Array("asd","asd","asd","asd","asd","asd","asd","asd","asd","asd","asd");
        Betrag[7] = new Array("asd","asd","asd","asd","asd","asd","asd","asd","asd","asd","asd");
        Betrag[8] = new Array("asd","asd","asd","asd","asd","asd","asd","asd","asd","asd","asd");

          for(i=1; i<=8; i++){
            for(k=1; k<=10; k++){
              setTimeout(function schreiben(){document.getElementById(''+i+k+'').value= Betrag[i][k];}, 1000);
              //document.getElementById(''+i+k+'').value= Betrag[i][k];
            }
          }

编译器说：类型错误：无法读取属性'11'的未定义

the compiler says "TypeError: Cannot read property '11' of undefined"

如果我不会用的setTimeout（）函数的整个循环工作正常，但此功能Ive得到了这样的错误。

if i would not use the settimeout() function the whole loop is working fine, but with this function ive got this mistake..

推荐答案

您可以尝试这样的事情：

You can try something like this:

    var i = 1;
    var k = 1;
    var obj = setInterval( function () {
        document.getElementById(i + '' + k).value= Betrag[i][k];
        if(k <= 10)
           k++;
        else
        {
            k = 1;
            if(i<=8)
                 i++;
            else
                 clearInterval(obj);
        }
    }, 1000);
