How to replace indexof (recommended)


Method: define indexof method through WXS, reference and use in page


WXS: named str.wxs , the defineindexof method of the export definition, named indexof

function defineIndexOf(str, val) {
 return str.indexOf(val);
module.exports = {
 indexOf: defineIndexOf


quote str.wxs , and name the module toolstr. In the following loop, you need to use the indexof method exported from toolstr

<wxs src="../../../../utils/str.wxs" module="toolStr" />
<view wx:for="{{list}}" wx:key="index"

 bindtap="clickf" data-id="{{}}">{{}}</view>

PS: look at the alternative method that wechat applet does not support indexof

Use lastIndexOf, but the order is the opposite of indexof
