mysql多圖怎麼同時上傳_小程式如何同時上傳多張圖檔？

元素上bindtap方法：(選擇圖檔)

chooseImgHandler: function (e) {

var that = this;

that.count_img = count_img; //允許上傳的圖檔數目

if (that.isGoing) return;

that.isGoing = true;

if (count_img) {

wx.chooseImage({

count: count_img,

sizeType: ['compressed'],

sourceType: ['album', 'camera'],

success: function (res) {

var tempFilePaths = res.tempFilePaths;

wx.showLoading();

that.uploadimg(tempFilePaths);

},

fail: function () {

// App.serverErrorTip("圖檔選擇失敗...");

that.isGoing = false;

}

})

} else {

App.serverErrorTip('已達到上傳圖檔上限啦~');

that.isClicking = false;

}

},

//拿到使用者選擇的圖檔的臨時檔案路徑數組以後，循環上傳到自己的伺服器

//上傳多圖

uploadimg: function (data) {

var that = this,

zero = 0,

i = data.i ? data.i : zero,

success = data.success ? data.success : zero,

url: '自己伺服器的位址',

name: 'file',

formData: {伺服器需要接受的參數},

success: function (resp) {

if (!resp.data || resp.data.indexOf("errcode") != -1) {

var msg = "";

try {

var json = eval("(" + resp.data + ")");
