Iterate JSON object with jquery
提问by el_pup_le
Why isn't the following working, inside a loop it never prints the url when myJSON is empty or not.
为什么以下不起作用,在循环中,无论 myJSON 是否为空,它都不会打印 url。
$.each($.parseJSON(myJSON), function(key,value){
alert(value.url);
});
for this JSON structure:
对于这个 JSON 结构:
[{"host":"foo","url":"bar"},{"host":"foos","url":"bars"}]
Edit: $.each is inside a loop which has instances/iterations where myJSON is empty if that makes a difference.
编辑: $.each 位于一个循环内,该循环具有实例/迭代,其中 myJSON 为空,如果这有所不同。

This works for me.
这对我有用。
var myJSON = '[{"host":"foo","url":"bar"},{"host":"foos","url":"bars"}]';
$.each($.parseJSON(myJSON), function(key,value){
alert(value.url);
});

var data = [{"host":"foo","url":"bar"},{"host":"foos","url":"bars"}]
$.each(data, function(i, item) {
alert(data[i].host);
});?
same as with the url.
与网址相同。
