KindEditor（V4.1.11）图片上传到服务器前判断图片大小、类型，如果不符合直接前端提示。

下面直接上代码：

<script charset="utf-8" src="kindeditor/kindeditor-all.js"></script>
<textarea name="content" style="width:100%;height:350px;visibility:hidden;"></textarea>
<script type="text/javascript">
	$(function(){
		KindEditor.ready(function(K) {
			editor = K.create('textarea[name="content"]', {
				allowFileManager : false,
				cssData: 'body {font-family:"微软雅黑";font-size:16px}',
				resizeType:1,
				allowImageRemote : false,
				maxfilesize: "3584",//图片大小限制
				img: {'sizemsg':'图片大小过大', 'typemsg':'文件类型有误' ,'type':['jpg','png','bmp','jpeg','gif'] },
				items: ["source", "|", "undo", "redo", "|", "fontname","fontsize","forecolor","hilitecolor","bold","italic","underline","lineheight","|","link","table","image"],
				afterUpload : function(url, data, name) {
					
				}
			});
		});
	});
</script>

修改kindeditor-all.js文件：

	maxfilesize = K.undef(self.maxfilesize, 2097152),
	imgSizeMsg = K.undef(self.img.sizemsg, 'image size error' ),
	imgTypeMsg = K.undef(self.img.typemsg, 'image type error' ),
	imgType = K.undef(self.img.type, [] ),

			var eve = e || window.event;
			if(typeof(eve.currentTarget) != "undefined"){
				var filesize = eve.currentTarget.files[0].size;
				var filename = eve.currentTarget.files[0].name;
				var file_ext=filename.split('.')[filename.split('.').length-1];
				//console.log('file_ext',  file_ext  );
				if(imgType.length>0){
					if(imgType.indexOf(file_ext.trim().toLowerCase())<0){
						alert(imgTypeMsg);
						return false;
					}
				}
				if(typeof(filesize) != "undefined" && filesize > maxfilesize){
					alert(imgSizeMsg);
					return false;
				}
			}

红框中为新增加的部分。
