html5 - How to get a specific value out of the FormData object -

so have code here

var form = document.getelementbyid("myform"); var formdata = new formdata(form); 

form contains 2 textfields, names "title" , "text". before submit form want value of title. tried

console.log(formdata.title); //undefined console.log(formdata[0]); //undefined console.log(formdata.get(title)); //title not defined console.log(formdata.get('title')); // formdata.get not function  var j = json.parse(formdata);    console.log(" formdata  > " + j);// uncaught syntaxerror: unexpected token o  var j = json.stringify(formdata);    console.log(" formdata  > " + j.title); // undefined 

how on god's green earth can specific value, based on name of input field ?

thanks

unfortunately, doesn't can in cross-browser friendly way. closest you'll find formdata.getall() isn't support in ie, edge or safari @ present.

i'd recommend leaving conversion formdata late possible in code (i.e. send request). libraries form-serialize can if need use/mangle form's value before submitting (alternatively use dom directly).
