wangEditor3使用AJAX异步上传图片

HTML：

<form  class="form form-horizontal" id="form-member-add" method="post" enctype="multipart/form-data">
	<input type="hidden"  value="${id }"  id="id" name="id" >
		<div class="row cl" style="margin: 20px;">
			<span class="c-red">*</span>标题：
				<input type="text" class="input-text radius"   id="title" name="title" >
		</div>
		<div class="row cl" style="margin: 20px;">
			<span class="c-red">*</span>内容：
			<div id="edit">
			</div>
		</div>
		<div class="row cl">
			<div class="col-xs-8 col-sm-9 col-xs-offset-4 col-sm-offset-3">
				 <input class="btn btn-primary radius" type="button" value="  提交  " onclick="subm(${type})" style="margin-left: 170px"> 
			</div>
		</div>
	</form>

JS：

<script type="text/javascript">

 function subm(type){

		var id=document.getElementById('id').value;
		var title = document.getElementById('title').value;
		var content = editor.txt.html();
		if(title==""||content==""){
			layer.msg('请把内容填写完整！',{icon:2,time:1000});
			return false;
		}
        
 		 $.ajax({
			type : "post",
			url : "newsAddPage.action",
			data : {
				"id":id,
				"title" : title,
				"content" : content,
				"type":type
			},
			success : function(result) {
				layer.msg('添加成功!',{icon:1,time:1000});
			},
			error : function(data) {
				$.Huimodalalert('修改失败！', 2000);
			}
		});  
	} 

	
	
</script> 
<script type="text/javascript">
    var E = window.wangEditor
    var editor = new E('#edit')
    
       editor.customConfig.uploadImgShowBase64 = true   // 使用 base64 保存图片
       
      
        
    // 隐藏“网络图片”tab
    editor.customConfig.showLinkImg = false
    editor.customConfig.menus = [
    'head',  // 标题
    'bold',  // 粗体
    'italic',  // 斜体
    'underline',  // 下划线
    'foreColor',  // 文字颜色
    'backColor',  // 背景颜色
    'list',  // 列表
    'justify',  // 对齐方式
    'quote',  // 引用
    'image',  // 插入图片
    'table',  // 表格
    'undo',  // 撤销
    'redo'  // 重复
    ]
    editor.create()
</script>

图片被转化为BASE64格式保存在了content里，在Controller中接收即可

图片保存在数据库中的格式为

<p><img src="data:image/jpeg;base64,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…………" style="max-width:100%;"><br></p>

若要在html中显示出来，直接将这个值传到前端，即可显示
