Here is the js function:

function multSubType(sel){
    var objSel = document.getElementById('subType'+sel);
    var valSel = new Arra开发者_如何学Goy();
    valSel.push(objSel.value);

}


Everytime the function executes, you're creating the array all over again. Move the variable declaration and array assignment outside the scope of the function:

var valSel = new Array();

function multSubType(sel) {
    var objSel = document.getElementById('subType' + sel);
    valSel.push(objSel.value);
}
