我收到jQuery [object Object]错误

Question

Hi I getting frustrated with this [object Object] thing. I have googled for quite a while today, and haven't found anything to solve my thing. this the part of the code that is returning this [object Object]

Thank you very much for your answer, time and consideration. :)

Answer 1

When you call .val with an argument, it returns a jQuery object. Your variables (lname, fname, mname) are objects. When you try to set the value of an element to an object, JavaScript will automatically convert it to a string.

alert() also requires a string, so giving it an object produces the same result.

alert({})
