选择选项在添加新选项时消失 [英] Select options disappearing when appending new option

问题描述

我当前正在创建一个界面，以双击双击一个选择元素中的一个选项，并将其附加到另一个选择元素中.

I'm currently creating a interface to select an option from one select element on double click, and append it to another select element.

我遇到的问题是这样做的时候，它已经添加并可见，但是所有其他选项在目标选择中都消失了，直到我单击该选项然后单击关闭.

The issue I am coming across is when doing so, it is added and visible, however all other options disappear in the destination select, until I click on the option and then click off.

我当前的实现如下:

$('body').on('dblclick', '#availableColumnsSelect > option', function (e) {

        var option = $(this);

        //Add option to destination
        displayColumnsSelect.append($('<option>', { value: option.val(), text: option.val() }));

        //Remove option from source
        option.remove();


        //Sort the select options
        sortSelect("#displayColumnsSelect");


        var optionsAvailable = $("#availableColumnsSelect > option:not([disabled])").length;


        if (optionsAvailable == 0) {
            $("#noSelectedText").removeClass('hidden');
        }
        $("#noSelectedText").addClass('hidden');
});

底层HTML正按照其应有的方式构建.

The underlying HTML is being constructed exactly how it should.

有什么想法吗?

推荐答案

如前所述，问题出在sortSelection函数上.我不太清楚为什么，但是无论我实际上不再需要此功能.

As pointed out the issue was with the sortSelection function. I'm not quite sure why, but regardless I don't actually require this function anymore.

删除所述功能已解决了问题:)

Removing said function has resolved the issue :)
