感谢Thomas W举了一个很好的例子，很好地编辑了这个看起来更好的东西。我只是稍微改变了它，但现在似乎完美无缺。托马斯现在已经学会并理解了一种新的方式来做某事，我不会再以另一种方式去做。:) 也会很快更改 clearbox(form) 中的代码。

谢谢

还要感谢 Thomas，因为您的示例我还能够将函数 bold_selected_tab() 更改为。我想我已经掌握了窍门。现在，如果 clearbox(form) 函数如下所示。

    function bold_selected_tab(tab_to_bold) {
        var x=1;
        while (x <= 10 ) {
            var box = document.getElementById("windows"+x);
            box.style.fontSize = "10pt ";
            x++;
        }

        var x=1;
        while (x <= 10 ) {
            var box = document.getElementById("windows"+x);
            box.style.fontWeight = "normal";
            x++;
        }

        tab_to_bold.style.fontWeight = "bold";
        tab_to_bold.style.fontSize = "12pt";
    }

当我说循环和数组时，我的意思是不要重复你的内部块 10 次。

var doneChecking = false;
for (var tab = 1; tab <= 10 && ! doneChecking; tab++) {
    if (tabspicked >= tab) {
        if (numbercount >= totals ){
            numbercount = 0;
            clearbox(this.form);
            doneChecking = true;
            break;
        }
        if (numbercount <= totals ){
            var elementId = "input_box"+tab;
            var urlIndex = numbercount + tab - 1;   // why?
            document.getElementById( elementId).value = document.getElementById( elementId).value + urls_1[ urlIndex] + " ";
        }
    }
}

你越早干净和正确地编码，你就会越早理解你真正想要做什么。您可以选择尝试和学习这些东西，也可以不选择。由你决定。

如果您尝试在 N 个文本框中分发以空格分隔的输入字符串，则可以执行以下操作。

var boxNum = 1;
var numBoxes = tabspicked;  // are these Boxes or Tabs? I'm calling them Boxes.
for (var url : urls_1) {
    // add to Current Box.
    var box = document.getElementById( "input_box"+boxNum);
    box.value = box.value + urls + " ";

    // advance Box, rotating around the N boxes.
    boxNum += 1;
    if (boxNum > numBoxes) boxNum = 1;
}

这应该是一种简单的方法。看看你是怎么做的。
