Recently I’ve been working on courier integration, submitting data as json and getting json data back. As shown below, what’s displayed is a json array, and my head immediately ached — before it was only json data, json arrays… After all kinds of attempts, data.kind had data but data.track_data had none, which was very strange. It seems a json array can’t be parsed that way. Next I tried a for loop, still useless. I couldn’t waste time on this, so I resolutely turned to Baidu (Google’s vpn is blocked), and after searching for a long while I finally found the answer: $.each. The official manual explains it like this: each(callback)
Execute a function with each matched element as the context. First, the first execution $.each(data.teack_data,function(a,b){ $.each(b,function(a1,b1){ //second execution alet(b1.info); //the data you need }); });
