Js implementation will cycle shows the JSON array in different div-CodePudding

Read the json array using ajax from the background, and an array of multiple data, different fields of each array into the corresponding div,
The code I wrote as follows, don't know what's the problem, always show don't come out? A great god, please give directions!!!!!
Var reobj=[
{" content ":" top-up CARDS, "
"Time" : "17-09-08"
},
{" content ":" millet hand ring, "
"Time" : "17-03-12"
},
{" content ":" IPTV, "
"Time" : "18-01-02"
}
];
The function fu (arr) {

Var STR="";
For (I=0, len=arr. Length; iSTR +='& lt; Div & gt; ';
STR +='& lt; Div & gt; '+ arr [I] content +' & lt;/div> ';
STR +='& lt; Div & gt; '+ arr [I] time +' & lt;/div> ';
STR +='& lt;/div> ';
}
}

Document. GetElementById (" box "). The innerHTML=fu (reobj);
</script>

}

CodePudding user response:

STR in a function, the scope is only in this way, you can remove the var in front of, thus become a global variable, can call, or in your method returns a STR
