使用jQuery填充数据库中的选择框

Question

I am trying to populate a select box from values from a mysql database, using jQuery.

db call:

<?php 
include 'db.php';
$con = mysql_connect($host,$user,$pass);
$dbs = mysql_select_db($databaseName, $con);

$tableName = "tbl_title";
$result = mysql_query("SELECT * FROM $tableName");

$data = array();
while ( $row = mysql_fetch_row($result) )
{
    $data[] = $row;
}
//echo json_encode( $data );    
?>

HTML:

<select id="a1_title">
  <option>Default</option>
</select>

There are a bunch of examples that I have found, but nothing specifically related to what I am looking for, unless the force is not with me today.

Is there a link someone can point me to?

The below script will load the dropdown list from the JSON received from the PHP Page.

$(function(){

  var items="";
  $.getJSON("yourPHPPage.php",function(data){

    $.each(data,function(index,item) 
    {
      items+="<option value='"+item.ID+"'>"+item.Name+"</option>";
    });
    $("#a1_title").html(items); 
  });

});

Assuming the received JSON is in this format

[ { "ID" :"1", "Name":"Scott"},{ "ID":"2", "Name":"Jon"} ]

Another thing i noticed is that you are doing SELECT * FROM table name to get the items. I do not think you should do that. You should do only two columns (ID & NAME , if you you have those columns in your table.).

Here is a JSFiddle example to show how to fetch data from the JSON.
