這篇文章將為大家詳細講解有關微信小程序之template模板的示例分析,小編覺得挺實用的,因此分享給大家做個參考,希望大家閱讀完這篇文章后可以有所收獲。
微信小程序 template模板
首先看一些官方的一些介紹。
模板:模板功能是通過對template 標簽的屬性 name=”” 去創建不同模板,通過is=”name的值”來使用。


通過上面兩張圖,大概能看出,使用模板可以為大量類似的布局帶來便利。下面看一下我自己的一個Demo.
先放出效果圖(數據來自聚合數據)



可以看到,除了選項個數的差別之外,其他布局是相同的。
下面的每一道題的模板。
<template name="carItem"> <view class="timu"> <view class="title">第pw_item.id題</view> <view class='question'>pw_item.question</view> <view class="img" wx:if="pw_item.url!=''"><image src="pw_item.url" /></view> <view class='select'>A:pw_item.item1</view> <view class='select'>B:pw_item.item2</view> <view class='select' wx:if="pw_item.item3!=''">C:pw_item.item3</view> <view class='select' wx:if="pw_item.item4!=''">D:pw_item.item4</view> <view class='content'>答案:pw_item.answer</view> <view class='content'>解釋:pw_item.explains</view> </view> </template>
在我們上面的代碼中,除了使用template標簽定義模板外,還是用了條件渲染。例如當題目為判斷題的時候。CD選項是沒有數據的,所以就不能顯示出來,我們可以通過if語句判斷是否為空來決定顯示與否。
下面放出代碼。
CarUtils.js
/**

function request(url, subject, model, testType, success, fail) {
if (typeof success != 'function' || typeof fail != 'function') {
return
}
wx.request({

data: {

model: model,
testType: testType,
},
success: function (res) {
if (res.data.error_code == 0) {
console.log("獲取數據成功"),
success(res.data)
} else {
wx.showModal({
title: '提示',
content: 'res.data.reason'+'請重新選擇',
success: function (res) {
if (res.confirm) {
console.log('用戶點擊確定')
}
}
})
console.log("失敗原因" + res.data.reason)
fail(res.data.reason)
}
},
fail: function () {
fail('網絡出現問題')
},
})
}
function getanswer(url,success,fail){
if( typeof success != 'function' || typeof fail != 'function' ) {
return
}
wx.request({

},
success: function(res){
if( res.data.error_code == 0 ) {
console.log("獲取數據成功"),
success( res.data )
} else {
console.log("失敗原因"+res.data.reason)
fail( res.data.reason )
}
},
fail: function() {
fail( '網絡出現問題' )
},
})
}
module.exports = {
