Question

我试图让一个div显示一个表格，同时模糊该区域周围的区域，就像一个模态。

这个想法在Facebook中用于关注状态框并模糊框周围的其他区域

Answer 1

StackOverflow 不是编码服务。然而，这很有趣，所以我想我会玩一点。传统上你应该在你自己的上尝试这个，然后问你是否有问题，展示你的工作。在大多数情况下，如果您无法证明自己至少试图自己解决问题，那么您不应该期望别人为您编写代码。

所有写的......

您可以使用clone()复制所需的焦点区域，然后将其覆盖在原始容器的其余部分上。然后模糊容器。这样，模糊不会改变clone()。

＆＃13;

$('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
 	
if ($('.popped').is(':visible')) {

		$('.popped').fadeOut(500); //remove clone if it's visible
    
		} else {
    
    $(this).clone().addClass('popped') //clone the target
  	.appendTo("body").css({ //move clone into position
    		left: position.left,
    		top: position.top 
  		})
      .text(theText + ' ::  left: ' + position.left + ', Top: ' + position.top);
      
    }
  
$('#wrap').toggleClass('blurred'); //blur the main container
});

＆＃13;

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; }

＆＃13;

<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>

＆＃13;

这将读取被单击的div的ID，并将克隆该div并将克隆放置在视口内的类似位置。您可以轻松地将其更改为按钮单击或其他事件。

对于每种情况，显然需要一些调整，但总体来说这种方法可能有效。

使用jQuery dialog()，例如以下从jQueryUI网站获取的代码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.!#$%&'*+\/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$/,
    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])+$/i, "Username may consist of a-z, 0-9, underscores, spaces and must begin with a letter.");
    valid = valid && checkRegexp(email, emailRegex, "eg. ui@jquery.com");
    valid = valid && checkRegexp(password, /^([0-9a-zA-Z])+$/, "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({
    autoOpen: false,
    height: 400,
    width: 350,
    modal: true,
    buttons: {
      "Create an account": addUser,
      Cancel: function() {

      }
    },
    close: function() {
      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() {
    dialog.dialog("open");
  });
});

专注于div和模糊区域就像模态一样
