JQuery: Dynamically create select Tag

Question

I am using JQuery to dynamically (based on user choice) create tag. User enters require options in a text box and my code creates select tag of it. Script is:

Answer 1

<!-- Create Dropdown -->
/* 1- First get total numbers of SELECT tags used in your page to avoid elements name/id issues.
 * 2- Get all OPTIONS user entered with comma separator into a text box.
 * 3- Split user OPTIONS and make an array of these OPTIONS.
 * 4- Create SELECT code.
 * 5- Appent it into the temp div (a hidden div in your page).
 * 6- Then get that code.
 * 7- Now append code to your actual div.
 * 8- Filnally make empty the temp div therfore it will be like a new container for next SELECT tag.
 */

total = $("select").size() + 1;                                         // 1-
var myoptions = $("#myoptions").val();                                  // 2-
var data = myoptions.split(',');                                        // 3-
var s = $("<select id=\""+total+"\" name=\""+total+"\" />");            // 4-
for(var val in data) {
    $("<option />", {value: val, text: data[val]}).appendTo(s);
}
s.appendTo("#tempselect");                                              // 5-
var getselectcode = $("#tempselect").html();                            // 6-
$("#msj_form").append(appendLabel+"<td>"+getselectcode+"</td></tr>");   // 7-
$("#tempselect").html('');                                              // 8-

<div style="display:none;" id="tempselect"></div>                       // Temp div

Answer 2

var html = '<tr><td><label for="select" style="text-transform:   none;">Label_name</label></td>'
            +'<td><select name="select" id="">'
            +'<option>Choose number..</option>'
            +'<option value="0">1</option>'
            +'<option value="1>2</option>'
            +'<option value="2">3</option>'
            +'</select></td></tr>';

Let's suppose, the id of table = table_id

$('#table_id').append(html);
$('#table_id').trigger('create');

What i get is, if you don't call trigger(), the design of your select looks completely messed up..

Answer 3

Slight amendment to the answer by Ravi - appending each element one by one is a surprisingly high cost operation.

var s = $("<select id=\"selectId\" name=\"selectName\" />");
var opts = [];
for(var val in data) {
    opts.push( $("<option />", {value: val, text: data[val]}));
}

opts.appendTo(s);

Answer 4

var s = $("<select id=\"selectId\" name=\"selectName\" />");
for(var val in data) {
    $("<option />", {value: val, text: data[val]}).appendTo(s);
}

after the for loop, wrap all the content with TableRow and Cells like this , Jquery Wrap()

$(s).wrap('<table><tr><td></td></tr></table>');
