Ajax追加数据以选择

Question

I need to add the data to the database and meanwhile load into a select options menu, I successfully added the data and when loading the data gets duplicated in the options menu

function manageRow(data) {
    var rows = '';
    $.each( data, function( i, o ) {
        rows += '<option>'+o.salary_wage+'</option>';
    });
    $(".selectpicker111").append(rows);
}

Answer 1

Try this ;)

$("selector").append(rows);

This will append options to existing options and you will get duplicate options.

There are 2 ways to get rid of duplicate options:

Option 1:

Remove existing options before adding options using empty and then you can add options using either append or html.

$("selector").empty();

Option 2:

Replace existing options with new options using html

$("selector").html(newOptions);

In your case:

$(".selectpicker111").html(rows);
