I'm writing a function for dynamic creation of forms with jQuery. Now I stuck at due the selected parameter won't show up by any reason. Here's a Fiddle .
I don't assume this to be a big deal, however I got stuck.
// Creates select element with N options.
// options is an array with options
// name is the elements ID as a string
// selected, optionally, is the selected option. must be the same type as in options
function make_dynamic_select( options, name, selected ){
select = "<select id='' type='' size ='1', name='" + name + "'>"
options.forEach(function(option){
// a little debug
console.log(typeof option,option," === ",typeof selected,selected,(option === selected))
// append the option
select += (option === selected)? "<option selected>":"<option>" + option + "</option>"
});
return select += "</select>"
};
You are not generating string correctly.
Use
select += (option === selected ? "<option selected>":"<option>" ) + option + "</option>";
Here is a DEMO .
function make_dynamic_select( options, name, selected ){
select = "<select id='' type='' size ='1', name='" + name + "'>"
options.forEach(function(option){
console.log(typeof option,option," === ",typeof selected,selected,(option === selected))
console.log(option === selected)
select += (option === selected)? "<option selected>"+option+"</option>":"<option>" + option + "</option>"
})
select += "</select>"
return select
};
$("#foo").append(make_dynamic_select([1,2,3],"bar",2));
