如何在函数内调用this.setData
function geyan(info) {
| this.setData({ note: info })
}
调用时提示：
Cannot read property ‘setData’ of undefined
this的指向是不是不对？怎么改正？

试下
geyan(info) {
| this.setData({ note: info })
}
function getPage(name){
var pagesArray = getCurrentPages() || []
for(var i = 0; i < pagesArray.length; i++){
var route = pagesArray[i].route;
var page_name = route.split(“/”).pop()
if (name == page_name) {
return pagesArray[i];
}
}
return null;
}
getPage(“page_name”).setdata()
let self = this;
放在哪里
let self = this;
function geyan(info) {
| self.setData({ note: info })
}
