</Panel>

• 读取本地图片并转成base64

_convertImageToBase64: function (filePath) {return new Promise(function (resolve, reject) {// 创建一个XMLHttpRequest对象var xhr = new XMLHttpRequest();// 配置请求，使用GET方法获取文件xhr.open("GET", filePath, true);// 设置响应类型为blob（二进制数据）xhr.responseType = "blob";// 注册加载完成的回调函数xhr.onload = function () {if (xhr.status === 200) {// 读取到的文件数据var blob = xhr.response;// 创建一个FileReader对象var reader = new FileReader();// 注册读取完成的回调函数reader.onloadend = function () {// 获取Base64编码的文件内容var base64Data = reader.result;resolve(base64Data);};// 读取blob数据为Base64编码reader.readAsDataURL(blob);} else {reject(new Error("Failed to load the image."));}};// 注册错误回调函数xhr.onerror = function () {reject(new Error("Failed to make the request."));};// 发送请求xhr.send();});
}

• onInit中调用

// 调用函数将文件转换为base64编码
this._convertImageToBase64("img/2.jpg").then(function (base64Data) {that.getView().setModel(new JSONModel({ "imgurl": base64Data }))}).catch(function (error) {console.error(error);});
