Question

onchange="document.forms[0].action = 'policyTypeSelection.do?method=policyTypeSelection'; document.forms[0].submit(); optionCheck(this);">

optionCheck(this);是Java Script：

function optionCheck(frm) {
    var i, len, optionVal, helpDiv, btnStatus,
    selectOptions = document.getElementById("options").submit();

    // loop through the options in case there
    // are multiple selected values
    for (i = 0, len = selectOptions.options.length; i < len; i++) {

        // get the selected option id
        optionVal = selectOptions.options[i].id;

        // find the corresponding help div
        helpDiv = document.getElementById("help");
        Statussecond = document.getElementById("second");
        Statusfirst = document.getElementById("first");

        // move on if we didn't find one
        if (!helpDiv) { continue; }

        // set CSS classes to show/hide help div
        if (selectOptions.options[i].selected) {

            helpDiv.className = "helpTextShow";
            Statussecond.className = "hiddenShow";
            Statusfirst.className = "none";

        }
    }
}

Answer 1

document.getElementById（＆＃34; options＆＃34;）。submit（）应更改为 document.getElementsByTagName（＆＃34;选项＆＃34）

在检查之前提交是不合理的。如果document.forms [0] .submit（）提交表单，页面将被重新加载，并且绝不会执行optionCheck（this）。

打开JavaScript时运行document.forms [0] .submit（）;
