小编use*_*394的帖子

我注意到extjs带有3到4个默认主题/皮肤.如何在主题之间选择或切换？

我想更改蓝色以选择灰色主题或其他内容.

谢谢

如何使用jquery捕获500错误消息？我想继续检查500错误消息,直到它发生变化,并在50秒后超时.

我使用下面的代码尝试捕获并检查500错误消息但它似乎没有捕获500错误消息.我可以在萤火虫中看到它

$.ajax({
    statusCode: {
        500: function() {
            alert(" 500 data still loading");
            console.log('500 ');
        }
    }
}); 

我正在使用Datatables,我有以下代码来生成表.我想显示read,write,execute和admin值的复选框.如果该值等于1,我想要选中复选框.如果未选中0复选框.

使用Javascript

<script type="text/javascript" charset="utf-8">
            $(document).ready(function() {
                var oTable = $('#example').dataTable( {
                     "sScrollY": "500px",                                
                    "bPaginate": false,
                    "bProcessing": true,
                    "sAjaxSource": "sources/sample.json"
                } );


            } );
        </script>

HTML

<table cellpadding="0" cellspacing="0" border="0" class="display" id="example">
                    <thead>
                        <tr>
                            <th width="20%">Browser</th>
                            <th width="25%">Read</th>
                            <th width="25%">Write</th>
                            <th width="15%">Execute</th>
                            <th width="15%">Admin</th>
                        </tr>
                    </thead>
                    <tbody>

                    </tbody>
                    </table>

JSON

{ "aaData": [
    ["Trident","0","0","0","1"],
    ["Trident","0","1","0","0"],
    ["Trident","0","0","1","1"],
    ["Trident","0","0","1","1"],
    ["Trident","0","0","1","1"],
    ["Trident","0","0","0","0"],
    ["Gecko","1","1","1","1"],
    ["Gecko","0","0","0","1"],
    ["Other browsers","1","0","0","U"]
] }

我试图关闭并使用jquery打开引导工具提示切换.但它似乎没有正常工作.我注意到一旦引导工具提示被关闭,它就不会再将工具提示再次打开.如何重新启用工具提示？感谢您的帮助

 .fa-3x {
  background-color: yellow;
}
.fa-lg {
  background-color: blue;
}
.toggle-button-on {
  color: green;
}
.toggle-button-off {
  color: red;
}  

$(document).ready(function() {
  $("ul.nav li ").click(function() {
$(this).toggleClass("toggle-button-on").find(".fa-3x").removeClass("fa-3x").addClass("fa-lg").css("border", "3px solid red");
  });
  $(".nav").on("click", ".toggle-button-on", function() {
$(".toggle-button-on").toggleClass("toggle-button-on toggle-button-off");
$(".nav .fa-3x").toggleClass("fa-3x fa-lg");
$('[data-toggle="tooltip"]').tooltip();
  });
  $(".nav").on("click", ".toggle-button-off", function() {
$(".toggle-button-off").toggleClass("toggle-button-off toggle-button-on");
$(".nav .fa-lg").toggleClass("fa-lg fa-3x");
 $('[data-toggle="tooltip"]').tooltip('disable');
   // $('[rel=tooltip]').tooltip('disable') // Hide and destroy tooltips
  });
});
