对GridView的行加颜色并弹出Kindeditor的实现思路

前台代码:

复制代码代码如下:

function tureDelete() {

if (confirm('真的要删除吗?') == false)

{ return false;}

}

function showdiv()

{

document.getElementByIdx_x("show1").style.display = "block";

document.getElementByIdx_x("showDiv").style.display = "block";

}

</script>

KindEditor.ready(function (K) {

var editor1 = K.create('#content1', {

cssPath: 'Kindeditor/plugins/code/prettify.css',

uploadJson: 'Kindeditor/asp.net/upload_json.ashx',

fileManagerJson: 'Kindeditor/asp.net/file_manager_json.ashx',

allowFileManager: true,

afterCreate: function () {

var self = this;

K.ctrl(document, 13, function () {

self.sync();

K('form[name=example]')[0].submit();

});

K.ctrl(self.edit.doc, 13, function () {

self.sync();

K('form[name=example]')[0].submit();

});

}

});

prettyPrint();

});

</script>

#showDiv {

position:absolute;

top:50%;

left:50%;

margin-left:-350px;

margin-top:-250px;

}

</style>

</head>
