How to use the evt.getImageLocalUrlPrefix function in evt

fixNoteContentForSend: function(content) {
		if(!content) {
			return content;
		}

		// console.log(Evt.localUrl + '/api/file/getImage');
		// console.log(content);
		var reg = new RegExp(Evt.getImageLocalUrlPrefix(), 'g');

		var reg3 = new RegExp(Evt.getAllAttachsLocalUrlPrefix(), 'g');
		content = content.replace(reg3, Evt.leanoteUrl + '/api/file/getAllAttachs');

	},

// 1. 先得到附件
		var attachs = note.Attachs || [];
		for(var i in attachs) {
			var attach = attachs[i];
			attach.IsAttach = true;
		}

		// 1. 先得到图片

		// 得到图片信息, 通过内容
		// http://localhost:8002/api/file/getImage?fileId=xxxxxx, 得到fileId, 查询数据库, 得到图片
		// console.log(content);
		// console.log(Evt.localUrl + '/api/file/getImage?fileId=([0-9a-zA-Z]{24})');
		// var reg = new RegExp(Evt.localUrl + "/api/file/getImage\\?fileId=([0-9a-zA-Z]{24})", 'g');
		var reg = new RegExp(Evt.getImageLocalUrlPrefix() + "\\?fileId=([0-9a-zA-Z]{24})", 'g');
		var fileIds = [];
		// var fileIdsMap = {}; // 防止多个
		while((result = reg.exec(content)) != null) {
			// result = [所有, 子表达式1, 子表达式2]
			if(result && result.length > 1) {
	            // console.log(result);
				var fileId = result[1];
				fileIds.push(fileId);
			}
        }
        var files = []; // {localFileId: "must", fileId: "", hasBody: true, filename: "xx.png"}
        if(fileIds.length > 0) {
        	// 得到所有的图片
        	File.getAllImages(fileIds, function(images) {
        		// attach与图片结合
        		if(images) {

fixNoteContent: function(content) {
		if(!content) {
			return content;
		}
		// https, http都行
		var url = Evt.leanoteUrl.replace('https', 'https*');

		// http://leanote.com/file/outputImage?fileId=54f9079f38f4115c0200001b
		var reg0 = new RegExp(url + '/file/outputImage', 'g');
		content = content.replace(reg0, Evt.getImageLocalUrlPrefix());

		var reg3 = new RegExp(url + '/attach/download?attachId', 'g');
		content = content.replace(reg3, Evt.getAttachLocalUrlPrefix() + '?fileId');

		// 无用
		// api/file/getAllAttachs?noteId=xxxxxxxxx, 这里的noteId是服务器上的noteId啊
		var reg4 = new RegExp(url + '/api/file/getAllAttachs', 'g');
