在外部单击时关闭弹出式div [英] Close popup div when clicked outside

问题描述

我有一个弹出div，仅在单击特定按钮时才显示.单击同一按钮时，它甚至隐藏.我的问题是，当我在外面的任何地方单击时，我也想隐藏div.我之所以无法这样做，是因为popup div位于主包装器类中，并且无法通过在包装器类上使用click事件并将其隐藏来做到这一点. 这是我的代码:

I have a popup div that shows only when clicked on particular button. It even hides when clicked on the same button. My problem is, i also want to hide div when clicked anywhere outside. I am not able to do so because the popup div is inside the main wrapper class and can't do so by using click event on the wrapper class and making it hide. This is my code:

function showHide() {
    var ele = document.getElementById("div_fieldWorkers");

    if (ele.style.display == "block") {           
        ele.style.display = "none";
    } else {
        ele.style.display = "block";      
    }
}

<input type="button" value="Add Field Worker" id="btnFieldWorkers" onclick="return showHide();" class="btn btn-primary" />

只是一个摘要:验证是否存在null和未定义的js错误.

Just a snippet: Validate for null and undefined js errors if any.

标记:

<div id="div_fieldWorkers" class="form_size" style='display:none;' class='noclick'><span class='noclick'>Hello How are you?</span></div>
<input
    type="button"
    value="Add Field Worker"
    id="btnFieldWorkers"
    class="btn btn-primary" />

Javascript:

Javascript:

 $('#btnFieldWorkers').bind("click", ToggleDisplay);

function ToggleDisplay() {
    if ($("#div_fieldWorkers").data('shown'))
        hide();
    else 
        display();
}

function display() {    
    if ($("#div_fieldWorkers").children().length > 0) {
        $("#div_fieldWorkers").fadeIn(500, function() {
            $(document).bind("click", function() {hide(); });            
            $("#div_fieldWorkers").data('shown', true)});         
    }  
}

function hide() {   
    if (window.event.toElement.className != 'noclick') {
        $("#div_fieldWorkers").fadeOut(500, function() {
            $(document).unbind("click");
            $("#div_fieldWorkers").data('shown', false);                
        });
    }
}
