it works when I write the event directly on click,
@click="diary.ispraise=1-diary.ispraise,diary.countpraise+=2*diary.ispraise-1" when changing to a function to pass a value, I don"t know how to write it. I"d like to ask for advice. no, no, no.
@click="myPra(diary.ispraise,diary.countpraise)"js:
myPra:function(a,b){
a=1-a;
b+=2*a-1;
}you can't pass a value directly
@click="myPra(diary)"myPra:function(diary){
diary.ispraise=1-diary.ispraise;
diary.countpraise+=2*diary.ispraise-1;
} @ click= "myPra (diary.ispraise,diary.countpraise)" so there is no problem.
only if you make sure that you already have the diary object in your data data, and that you already have the two attributes ispraise,countpraise in the diary object
data: {
diary:{
ispraise: ,
countpraise:
}}
page, there will be no error.
@ click= "myPra (diary.ispraise,diary.countpraise)"
