Question

<span class="answerBox">
<a name="checkboxtag" class="largecheckbox" onclick="selectQuestionAnswer(this);"></a>
<input name="answers" value="8ad6a4124641ec5001464d856b23436c" class="checkbox displaynone" type="radio">
</span>

我尝试过使用.prop（）

jQuery('input:checkbox[value="8ad6a4124641ec5001464d856b23436c"]').prop("checked", true);

试图触发点击：

jQuery('input:checkbox[value="8ad6a4124641ec5001464d856b23436c"]').trigger('click');

尝试编辑其兄弟的课程（因为点击它会改变兄弟姐妹的课程，而不是别的）：

jQuery('input:checkbox[value="8ad6a4124641ec5001464d856b23436c"]').siblings('.largecheckbox').trigger('click');

然后我不确定我是否正确选择它。我试图在复选框上切换高亮显示，但它没有做任何事情..

jQuery('input:checkbox[value="8ad6a4124641ec5001464d856b23436c"]').siblings('.largecheckbox').toggle('highlight');
jQuery('input:checkbox[value="8ad6a4124641ec5001464d856b23436c"]').toggle('highlight');

是否无法选中此复选框？我昨天和今天一整天都在努力。

感谢阅读和任何帮助！

编辑：你们是众神。有用。我使用了jQuery('input:radio[value="8ad6a4124641ec5001464d856b23436c"]').siblings().toggle('highlight');

确保它能够正常工作。谢谢。然后我使用了触发器（'click'）;它做了。我所要做的就是使用无线电选择器选择它。谢谢大家的努力。

您正尝试使用复选框选择器

更改<input type="radio">

将一个或另一个修复为应该是什么

当您更改为

时，您的代码可以正常工作

<input name="answers" value="8ad6a4124641ec5001464d856b23436c" type="checkbox">

如果您想作为广播使用:radio选择器

你的第一个解决方案非常接近。只需将冒号更改为句点。

double Rate1 = Weeks * ECONOMY_WEEKLY;
    double Rate2 = (Weeks * ECONOMY_WEEKLY) + (Days * ECONOMY_DAILY);
    double Rate3 = (Days * ECONOMY_DAILY);
    switch (FirstTypeLetter) {
        case 'E':
            if ((Rate1 > Rate2) & (Rate1 > Rate3)) {
                System.out.println("This is the best rate for a" + " " + color + " " + Type + " vehicle for" + " " + Days + "days:" + Rate1);
            }
            else if ((Rate2 > Rate1) & (Rate2 > Rate3)){
                System.out.println("This is the best rate for a" + " " + color + " " + Type + " vehicle for" + " " + Days + "days:" + Rate2);
            }
            else if ((Rate3 > Rate2) & (Rate3 > Rate1)) {
                System.out.println("This is the best rate for a" + " " + color + " " + Type + " vehicle for" + " " + Days + "days:" + Rate3);
            }
            break;
        case 'F':
            double FullRate1 = Weeks * FULL_WEEKLY;
            double FullRate2 = (Weeks * FULL_WEEKLY) + (Days * FULL_DAILY);
            double FullRate3 = (Days * ECONOMY_DAILY);
            if ((Rate1 > Rate2) & (Rate1 > Rate3)) {
                System.out.println("This is the best rate for a" + " " + color + " " + Type + " vehicle for" + " " + Days + "days:" + FullRate1);
            }
            else if ((FullRate2 > FullRate1) & (FullRate2 > FullRate3)) {
                System.out.println("This is the best rate for a" + " " + color + " " + Type + " vehicle for" + " " + Days + "days:" + FullRate2);
            }
            else if ((FullRate3 > FullRate1) & (FullRate3 > FullRate2)) {
                System.out.println("This is the best rate for a" + " " + color + " " + Type + " vehicle for" + " " + Days + "days:" + FullRate3);
            }
            break;
        default:
            System.out.println("Try Again!");
            break;
       }

我正在使用此函数来检查您需要传递复选框的jquery对象所需的任何复选框

function toggleCheck(elm, checked) {
    if (elm.is(":checked") != checked) {
        elm.click();
    }
}

toggleCheck($('[name="answers]'), true) // will check if not already checked
toggleCheck($('[name="answers]'), false) // will un check if already checked

Answer 4

您没有匹配的元素，为changed$('input:radio[value="8ad6a4124641ec5001464d856b23436c"]')，

Answer 5

将收音机更改为复选框后，请尝试此操作。

$(function(){
    $(".largecheckbox").click(function(){
        $(this).next("input:checkbox").attr("checked",true);
    });
});

如何根据值选择和检查这些类型的复选框？
