Can I use a variable to pass a json string?

Question

This code works:

$(this).load($('.pageloadlabel', this).attr('href'), {category: 1});

This code doesn't work:

var data = '{category: 1}';
$(this).load($('.pageloadlabel', this).attr('href'), data);

The question is, how can I make it work?

Answer 1

It's not JSON, it's a javascript object.

var data = { category: 1 };

If you have a string, you would have to convert it to a object .

And notice that your string is not a valid JSON, see the link for more details.

Answer 2

删除引号，加载函数需要一个对象，而不是字符串。

Answer 3

Your data is not a Javascript object but a string, you can convert it to object by eval eg

data = eval('(' + data + ')');

but eval is considered dangerous, so better to parse string as JSON eg

data = JSON.parse(data)

For JSON lib you can use json2

Answer 4

Have you tried to use eval() on data?

var data = '{category: 1}';
$(this).load($('.pageloadlabel', this).attr('href'), eval(data));
