使用jQuery dialog()，就像從jQueryUI網站採取了下面的代碼，你可以找到here：

$(function() { 
 
    var dialog, form, 
 

 
    // From http://www.whatwg.org/specs/web-apps/current-work/multipage/states-of-the-type-attribute.html#e-mail-state-%28type=email%29 
 
    emailRegex = /^[a-zA-Z0-9.!#$%&'*+\/=?^_`{|}~-][email protected][a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$/, 
 
    name = $("#name"), 
 
    email = $("#email"), 
 
    password = $("#password"), 
 
    allFields = $([]).add(name).add(email).add(password), 
 
    tips = $(".validateTips"); 
 

 
    function updateTips(t) { 
 
    tips 
 
     .text(t) 
 
     .addClass("ui-state-highlight"); 
 
    setTimeout(function() { 
 
     tips.removeClass("ui-state-highlight", 1500); 
 
    }, 500); 
 
    } 
 

 
    function checkLength(o, n, min, max) { 
 
    if (o.val().length > max || o.val().length < min) { 
 
     o.addClass("ui-state-error"); 
 
     updateTips("Length of " + n + " must be between " + 
 
     min + " and " + max + "."); 
 
     return false; 
 
    } else { 
 
     return true; 
 
    } 
 
    } 
 

 
    function checkRegexp(o, regexp, n) { 
 
    if (!(regexp.test(o.val()))) { 
 
     o.addClass("ui-state-error"); 
 
     updateTips(n); 
 
     return false; 
 
    } else { 
 
     return true; 
 
    } 
 
    } 
 

 
    function addUser() { 
 
    var valid = true; 
 
    allFields.removeClass("ui-state-error"); 
 

 
    valid = valid && checkLength(name, "username", 3, 16); 
 
    valid = valid && checkLength(email, "email", 6, 80); 
 
    valid = valid && checkLength(password, "password", 5, 16); 
 

 
    valid = valid && checkRegexp(name, /^[a-z]([0-9a-z_\s])+$/i, "Username may consist of a-z, 0-9, underscores, spaces and must begin with a letter."); 
 
    valid = valid && checkRegexp(email, emailRegex, "eg. [email protected]"); 
 
    valid = valid && checkRegexp(password, /^([0-9a-zA-Z])+$/, "Password field only allow : a-z 0-9"); 
 

 
    if (valid) { 
 
     $("#users tbody").append("<tr>" + 
 
     "<td>" + name.val() + "</td>" + 
 
     "<td>" + email.val() + "</td>" + 
 
     "<td>" + password.val() + "</td>" + 
 
     "</tr>"); 
 
     dialog.dialog("close"); 
 
    } 
 
    return valid; 
 
    } 
 

 
    dialog = $("#dialog-form").dialog({

     form[0].reset(); 
 
     allFields.removeClass("ui-state-error"); 
 
    } 
 
    }); 
 

 
    form = dialog.find("form").on("submit", function(event) { 
 
    event.preventDefault(); 
 
    addUser(); 
 
    }); 
 

 
    $("#create-user").button().on("click", function() {

「......模糊區域......」 – showdev

@showdev我明白你的意思了，謝謝指出。我剛剛更新了我的答案。這次模態對話框出現時，周圍區域變灰。 –

感謝您的更新！很好的例子。我認爲OP正在尋找實際[模糊背景]（https://codepen.io/chrisyap/pen/HCjzL）內容，但我可能會誤解。 – showdev

的StackOverflow是不編碼服務。不過，這很有趣，所以我想我會玩一下。傳統上你應該自己嘗試這個然後問你是否有問題，顯示你的工作。在大多數情況下，如果您無法證明您至少試圖自己解決問題，您不應該指望其他人爲您編寫代碼。

所有這一切被寫入.....

你可以使用clone()複製想要的對焦區域，然後覆蓋上原來的容器的其餘部分。然後模糊容器。這樣clone()不會被模糊所改變。

$('div').on('click', function() { 
 

 
var theDiv = $(this).attr('id'); //the ID of the div to focus 
 
var theText = $(this).text(); 
 
var position = $(this).position(); //gets current position of focus div 
 
    \t 
 
if ($('.popped').is(':visible')) { 
 

 
\t \t $('.popped').fadeOut(500); //remove clone if it's visible 
 
    
 
\t \t } else { 
 
    
 
    $(this).clone().addClass('popped') //clone the target 
 
    \t .appendTo("body").css({ //move clone into position 
 
    \t \t left: position.left, 
 
    \t \t top: position.top 
 
    \t \t }) 
 
     .text(theText + ' :: left: ' + position.left + ', Top: ' + position.top); 
 
     
 
    } 
 
    
 
$('#wrap').toggleClass('blurred'); //blur the main container 
 
});
body { background: #ddd; } 
 
#wrap { 
 
    position: relative; 
 
    margin: 10px; 
 
    text-align: center; 
 
    width: 500px; 
 
    transition: all .4s; 
 
} 
 

 
div { 
 
    position: relative; 
 
    margin: 5px auto; 
 
    background: #fff; 
 
    text-align: center; 
 
    padding: 5px 10px; 
 
    border: 1px solid #aaa; 
 
    text-transform: uppercase; 
 
    font-weight: bolder; 
 
    width: 100%; 
 
} 
 

 

 
    .popped { 
 
    position: absolute; 
 
    z-index: 5000; 
 
    width: 500px; /* same width ans main container (or original div) */ 
 
    margin: 15px 18px; /* compensates for blur -- blur distance times 2 */ 
 
    } 
 
    
 
    
 
    .blurred { 
 
    filter: blur(5px); 
 
    -webkit-filter: blur(5px); 
 
    -moz-filter: blur(5px); 
 
    opacity: 0.5; 
 
    transition: all .4s; 
 
    } 
 
    
 

 
h3 { text-align: center; font-weight: normal; text-transform: uppercase; font-size: 0.7em; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<section id="wrap" class=""> 
 
<div id="one">First div</div> 
 
<div id="two">This is number 2</div> 
 
<div id="three">A third Div</div> 
 
<div id="four">4th and final</div> 
 
    <h3>Click a row to focus on it</h3> 
 
</section>

這讀取被點擊，並克隆了一個DIV，並在視口內的類似位置的克隆的立場，即div的ID。你可以很容易地改變這個以使用按鈕點擊或其他事件。

這顯然是需要一些調整爲每種情況，但總體來說這種方法可能工作。
