/** * 生命周期函數(shù)--監(jiān)聽(tīng)頁(yè)面加載 */ onLoad: function (options) { this.initValidate()//驗(yàn)證規(guī)則函數(shù),初始化字段規(guī)則和字段提示信息 }, initValidate() { const rules = { userName: { //用戶名 required: true, minlength:2 }, password: { //密碼 required: true }, phone:{ //手機(jī)號(hào) required:true, tel:true } } const messages = { //提示信息 userName: { required: '請(qǐng)?zhí)顚?xiě)姓名', minlength:'請(qǐng)輸入正確的名稱' }, password: { required: '請(qǐng)?zhí)顚?xiě)密碼' }, phone:{ required:'請(qǐng)?zhí)顚?xiě)手機(jī)號(hào)', tel:'請(qǐng)?zhí)顚?xiě)正確的手機(jī)號(hào)' } } this.WxValidate = new WxValidate(rules, messages) }, //調(diào)用驗(yàn)證函數(shù) formSubmit: function (e) { console.log('form發(fā)生了submit事件，攜帶的數(shù)據(jù)為：', e.detail.value) const params = e.detail.value //校驗(yàn)表單 if (!this.WxValidate.checkForm(params)) { const error = this.WxValidate.errorList[0] console.log(error); return false } console.log("yes"); return true;}, |
值得注意的是： WxValidate的errorList列表返回的是一個(gè)對(duì)象。
而且驗(yàn)證的字段名應(yīng)該和表單組件對(duì)應(yīng)的name一一對(duì)應(yīng)。
以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持服務(wù)器之家。
