微信小程序动态增加按钮组件

这里的程序" title="微信小程序">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,

})

}

})

},

})
