这里的微信小程序动态加载是以按钮为例，主页面点击不同的按钮进入不同的子页面中，根据主页面的title来动态加载子页面按钮的数量以及值。
效果图：
wxml文件（注意wx:key="item"要写，不然它会有警告）：
<!--pages/plan/plans/plans.wxml-->
<view class="className" style="background-color: rgb(225, 218, 211); height:{{className_height}}px" wx:for="{{array}}" wx:key="item">
<button class="items" id="{{stv.id[index]}}">{{item.name}}</button>
</view>
这里起关键作用的是wx:for，这里是循环。
wxss文件：
/* pages/plan/plans/plans.wxss */
.items {
background-color: rosybrown;
width:60%;
}
js文件：
// pages/plan/hot/hot.js
Page({
data: {
},
onLoad: function (options) {
var that = this;
var arr = new Array();
if (options.title == "热门") {
var location1 = { name: "1" };
var location2 = { name: "2" };
var location3 = { name: "3" };
var location4 = { name: "4" };
var location5 = { name: "5" };
var location6 = { name: "6" };
arr.push(location1);
arr.push(location2);
arr.push(location3);
arr.push(location4);
arr.push(location5);
arr.push(location6);
console.log("OK");
} else {
var location1 = { name: "2" };
var location2 = { name: "4" };
var location3 = { name: "5" };
arr.push(location1);
arr.push(location2);
arr.push(location3);
}
wx.setNavigationBarTitle({title:'创建新计划--'+options.title});
wx.getSystemInfo({
success: function (res) {
that.setData({
//view
className_height: res.windowHeight / arr.length,
//btn
array: arr,
})
}
})
},
})
