<?php
$sql = "SELECT * FROM trucks WHERE status !='1' ORDER BY reg_date DESC";
$result = mysql_query($sql);
$cat=array();
while($row = mysql_fetch_array($result)){
	echo '<tr>
			<td>'.$row["truck_name"].'</td>
			<td>'.Getstate($row["state_id"]).'</td>
			<td>'.Getcity($row["city_id"]).'</td>
			
			<td class="col-medium center">
			<div class="btn-group btn-group-xs ">
			<a class="btn btn-inverse" style="cursor:pointer;" onclick="show_edit_menu(\''.$row["id"].'\',\''.$row["truck_name"].'\',\''.$row["state_id"].'\',\''.$row["city_id"].'\')"><i class="fa fa-edit icon-only"></i>Edit</a>

Answer 1

试试这个：

$("#state option[value='"+state_id+"']").attr("selected", true);

而不是

$("#state").val(state_id);
