Detailed explanation of the example code about react native click event

For example, if we define a TouchableOpacity click event, the method needs to receive a parameter value, as follows

_gotoSubClass(sectionID, rowID) { console.log("sectionID="+sectionID + "rowID=" + rowID); }

Then the onPress attribute of the TouchableOption component should be written like this:

 this._gotoSubClass(sectionID, rowID)}> {rowData.title} 
         

          Copy after login
         
        

or

 {rowData.title}  其中bind中的参数1：this代表的是上下文对象，后面跟的参数，对应私有方法中的参数顺序。
