本站的编辑器图片上传便是使用的这部分
Seajs 定义Tools模块
/**

define(function (require, exports, module) {
/**
* 截图粘贴
* @param selector
* @param callback
*/
exports.paste = function (selector, callback) {
document.querySelector(selector).addEventListener("paste", function (ev) {
var data = ev.clipboardData;
var items = (event.clipboardData || event.originalEvent.clipboardData).items;
for (var i in items) {
var item = items[i];
//如果是图片
if (item.kind === 'file' && item.type.indexOf('image') > -1) {

var reader = new FileReader();
//reader读取完成后，xhr上传
reader.onload = function (event) {
var base64 = event.target.result;
//ajax上传图片
//返回一个base64数据
var img = {type: item.type, kind: item.kind};
if (typeof callback === "function") {
callback(event.target.result, img, event);
}

element.addEventListener("drop", function (e) {

var files = e.dataTransfer.files;
for (var i = 0; i < files.length; i++) {
//回调文件
//alert("Drop " + file[i].name.toString());
var reader = new FileReader();
var item = files[i];
reader.onload = function (event) {
var base64 = event.target.result;

var img = {type: item.type, name: item.name};
if (typeof callback === "function") {

}
};
reader.readAsDataURL(files[i]);//reader
}
return false;
});
element.addEventListener("dragenter", function (e) {
e.stopPropagation();
e.preventDefault();
});
element.addEventListener("dragover", function (e) {
e.dataTransfer.dropEffect = "copy";
e.stopPropagation();
e.preventDefault();
});
document.body.addEventListener("dragover", function (e) {

}
/**
* 解析粘贴过来的内容，看是否有不是本站的图片,解析出来上传到本站
*/
exports.parseImg = function () {
}
});
使用方法：
//粘贴上传图片
Edtools.paste("#post_content", function (base64, image, event) {
$.post("{:url('api/uploader/upEditorImg')}",{base:base64}, function (ret) {
layer.msg(ret.msg);
if (ret.code === 1) {
//新一行的图片显示
editor.insertValue("\n![" + ret.data.title + "](" + ret.data.path + ")");
}
});
});
//拖拽上传图片
Edtools.drag("#post_content", function (base64, image, event) {
$.post("{:url('api/uploader/upEditorImg')}",{base:base64}, function (ret) {
layer.msg(ret.msg);
if (ret.code === 1) {
//新一行的图片显示
editor.insertValue("\n![" + ret.data.title + "](" + ret.data.path + ")");
}
});
});
