How to Convert Form Data to a JavaScript Object with jQuery
For convenience, you may want to automatically build a JavaScript object from your form without looping over each element. Utilizing jQuery's serializeArray method provides an effective solution but requires some processing to achieve the desired object format.
Solution:
The serializeArray method returns an array of objects representing each form element. To convert this to an object, leverage the following function:
function objectifyForm(formArray) { var returnArray = {}; for (var i = 0; i < formArray.length; i++) { returnArray[formArray[i]['name']] = formArray[i]['value']; } return returnArray; }
For instance, given the form elements:
<input type="text" name="name" value="John"> <input type="email" name="email" value="john@example.com">
The code will produce the object:
{ name: "John", email: "john@example.com" }
Note: Be mindful of hidden fields with the same name as actual inputs, as they may overwrite the values in the object.
