问题
Using JavaScript to split a date and rearrange the format.
Date is provided through a json feed as YYYY-MM-DD.
To get the date, I do:
var og_date = (v.report[totalItems -1].inspection_date);
console.log(og_date);
console log correctly shows the date, ie "2012-10-01".
Next, I try to split the date, for example:
console.log(og_date.value.split('-'));
And I get:
Uncaught TypeError: Cannot read property 'split' of undefined
Any ideas?
回答1:
Your question answers itself ;) If og_date contains the date, it's probably a string, so og_date.value is undefined.
Simply use og_date.split('-') instead of og_date.value.split('-')
回答2:
ogdate is itself a string, why are you trying to access it's value property that it doesn't have ?
console.log(og_date.split('-'));

og_date = "2012-10-01";
console.log(og_date); // => "2012-10-01"
console.log(og_date.split('-')); // => [ '2012', '10', '01' ]
og_date.value would only work if the date were stored as a property on the og_date object.
Such as: var og_date = {}; og_date.value="2012-10-01";
In that case, your original console.log would work.
