Ajax 提交KindEditor的数据
KindEditor.ready(function (K) {
var editor1 = K.create('#content', {
cssPath: '../js/plugins/code/prettify.css',
uploadJson: 'upload_json.ashx',
fileManagerJson: '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();
});
改代码就是官方给的，后来发现，第二次提交，这个content又有值了，甚是奇怪，后来在百度的帮助下，找到了原因，原理是需要在提交之前，异步一下编辑器的内容，改良后的代码如下：
KindEditor.ready(function (K) {
var editor1 = K.create('#content', {
cssPath: '../js/plugins/code/prettify.css',
uploadJson: 'upload_json.ashx',
fileManagerJson: '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();
});
},
afterBlur: function () { this.sync(); }
//这一步非常重要，如果遗漏，则后台无法接收到数据。
});
prettyPrint();
});
这样后台就可以正常接收数据了，下面是完整代码，也可以下载附件来看：
