javascript - 如何让禁用的按钮在单击时执行某些操作？ (JS)

Question

所以我有这段代码:

var delete_disabled = (parseInt(row.attr("data-state"), 10) === serverVars.obligationStateNotStarted) ? '' : 'disabled="disabled"';
        newHtml += "<button class=\"delete small\"" + delete_disabled + " title=\"" + labelDelete + "\"><i class=\"icon-trash\"></i></button>";

它检查是否满足某个条件，如果满足，则禁用该按钮，但是一旦禁用该按钮，我希望单击它时仍然会发生一些事情吗？我已经尝试了我能想到的一切，并希望得到一些建议。 预先感谢:)

除了单击禁用按钮时实际触发事件之外，您还可以在禁用按钮前面添加一个虚拟元素，并在该元素上添加与禁用状态关联的监听器。例如，

js

$(document).ready(function () {
/*this click listener could also be added as part of the disableButton function.*/
    $(document).on('click', '.click-div', function () {
        console.log('clicked');
        alert('clicked');
    });

    disableButton($('button'));
    //enableButton($('button'));

});

function disableButton($el){
    var wrapper = $el.wrap("<div class='wrapper'>").parent();
    wrapper.css({"display":"inline","position":"relative"});
    var divClick = $("<div class='click-div'>");
    divClick.css({"position":"absolute",
                  "top":0,
                  "height":"100%",
                  "width":"100%"
                 });
    wrapper.append(divClick);

    /*divClick.on('click', function () {
        console.log('clicked');
        alert('clicked');
    });*/
}

function enableButton($el){
    $el.next(".click-div").remove();
    $el.unwrap("<div class='wrapper'>");
    $el.prop("disabled",false);
}

html

<button disabled>test</button>
