How to add integer value from variable to hidden field by jquery

Question

I want add the return value from var Selectedvalue to hidden field id="Branchidhidden" in its value.

jQuery:

function Branch() {
    var Selectedvalue =  $( "#Branchitemtypeid option:selected" ).val(); //The return value is correct 
    $('#Branchidhidden').attr('value', Selectedvalue)
}

HTML:

<input type="hidden" id="Branchidhidden" name="Branchidhidden"  value=""/>

When I see the view-source value in hidden field is empty.

can you please post your full code ? I mean the select and options part too — Muhammad Usman

You need to set the value attribute: .attr('value', Selectedvalue) This is a duplicate question. — trincot

use .val(yourValue) on that input, but remove the value="" attribute from hidden input tag — Dawid Zbiński

use PROP/VAL instead of ATTR

function Branch() {
    var Selectedvalue =  $( "#Branchitemtypeid option:selected" ).val(); //The return value is correct 
    $('#Branchidhidden').prop('value', Selectedvalue);

    // or val
    $('#Branchidhidden').val(Selectedvalue);
}
