编辑这是我编写代码的方式。
<script>
$(document).ready(function () {
$("#country").change(
function () {
var options = {
url: "test.php",
type: "post",
dataType: "json",
data: "country=" + $(this).val(), //build your data string here

I will take the same example and modify and give you an answer.
我会以同样的例子并修改并给你一个答案。
<script>
$(document).ready(function () {
$("#country").change(
function () {
var options = {
url: "/path/to/your.php",
type: "post",
dataType: "json",
data: "country=" + $(this).val(), //build your data string here
success: function (json) {
$("#textbox").val(json.country);
}
};
$.ajax(options);
}
);
});
</script>
<select id="country" name="country">
<option value="Delhi" >India</option>
<option value="manila" >phil</option>
<option value="tokyo" >japan</option>
</select>
in order to capture the value on the server side in your php file
为了在您的 php 文件中捕获服务器端的值
$var = $_POST['country'];
$json = array('country' => $var);
header("Content-Type: application/json");
echo json_encode($json);
Updated code will return the countryback to the script via jsonand write to a <input type=textfield which has id=textbox
更新后的代码将返回country脚本通过json并写入<input type=text具有id=textbox
