官方文档中只有一行
wx.canvasToTempFilePath参数为一个对象包括canvasID,success,fail,complete，和wx.saveFile差不多；- wx.canvasToTempFilePath({
- canvasId: 'target',
- success: function success(res) {
- wx.saveFile({
- tempFilePath: res.tempFilePath,
- success: function success(res) {
- console.log('saved::' + res.savedFilePath);
- },
- complete: function fail(e) {
- console.log(e.errMsg);
- }
- });
- },
- complete: function complete(e) {
- console.log(e.errMsg);
- }
- });
