小程序在js里获取控件的两种方式
一种用 点+控件类名
var query = wx.createSelectorQuery(); //选择id var that = this; query.select('.progressBarCarrier').boundingClientRect(function (rect) { let width = rect.width
console.log("矩形:",rect)
}).exec();
另外一种用 #+控件id
let option = answers[idx] let optionName = "#opt" + bigIdx+idx var query = wx.createSelectorQuery(); //选择id var that = this; query.select(optionName).boundingClientRect(function (rect) { let height = rect.height console.log("选项尺寸:" + JSON.stringify(rect)) option.borderRadius = height console.log("选项字典:" + JSON.stringify(questions)) that.setData({ questionList: questions }) }).exec();
