Question

我有一个表单，允许用户选择付费频率（例如每小时）并显示年化因子（2080，每小时）。我的代码允许用户修改年度化因子，但我希望它只显示，而不是可编辑。有人可以帮忙吗？

代码：

function register() {
    document.all.NewFrequency.onchange = OnChange;
}

function Init() {
    var selectionValue = document.all.AnnualizingFactor;
    register();
    if (selectionValue.value == "") {
        OnChange();
    }
}

function OnChange() {
    var selectValue = document.all.NewFrequency;
    var selectionValue = document.all.AnnualizingFactor;
    if (selectValue.options[selectValue.selectedIndex].value == "Yearly" ) {
        selectionValue.value = "1";
    }
    if (selectValue.options[selectValue.selectedIndex].value == "Weekly") {
        selectionValue.value = "52";
    }
    if (selectValue.options[selectValue.selectedIndex].value == "Unit") {
        selectionValue.value = "2080";
    }
    if (selectValue.options[selectValue.selectedIndex].value == "SemiWeekly") {
        selectionValue.value = "104";
    }
    if (selectValue.options[selectValue.selectedIndex].value == "Semimonthly") {
        selectionValue.value = "24";
    }
    if (selectValue.options[selectValue.selectedIndex].value == "Quarterly") {
        selectionValue.value = "4";
    }
    if (selectValue.options[selectValue.selectedIndex].value == "Monthly") {
        selectionValue.value = "12";
    }
    if (selectValue.options[selectValue.selectedIndex].value == "Hourly") {
        selectionValue.value = "2080";
    }
    if (selectValue.options[selectValue.selectedIndex].value == "Daily") {
        selectionValue.value = "365";
    }
    if (selectValue.options[selectValue.selectedIndex].value == "Biweekly") {
        selectionValue.value = "26";
    }
    if (selectValue.options[selectValue.selectedIndex].value == "None") {
        selectionValue.value = "0";
    }
}

正如@ j08691所说，你必须只读标记字段：

<input type="text" readonly name="AnnualizingFactor" />

或以编程方式设置输入的readonly属性：

function Init() {
    var selectionValue = document.all.AnnualizingFactor;
    selectionValue.readonly = true;
    register();
    if (selectionValue.value == "") {
        OnChange();
    }
}

如何将结果单元格只读？
