Div对话内容的内容即使在Jquery Dialog未打开时也会显示

Question

我使用Grails 3.1.9作为平台，我的问题是当没有点击按钮添加项时，我可以看到页面底部对话框的内容，以及点击按钮时，内容从底部消失。我该如何防止这种情况发生？我们将非常感谢您提供的任何帮助。

点击添加项目按钮之前

单击“添加项目”按钮后

show.gsp代码是：

Answer 1

<div id="dialogEntry" title="Item Entry">

将其更改为：

<div id="dialogEntry" title="Item Entry" style="display:none;">

改变这个：

 document.getElementById("add").innerHTML =
                        $( "#dialogEntry" ).dialog({

到

 document.getElementById("add").innerHTML =
                        $( "#dialogEntry" ).show().dialog({

将其更改为：

text: "Cancel",
                                    click: function() {
                                        $( this ).dialog( "close" ).hide();
                                    }
