问题描述

我的表单中有一个单选按钮,当我输入参考号时,我可以使用 jQuery 获取相应的表单详细信息以及 source 值。我不知道如何将该值设置为单选按钮。

 < input type =radiong-model =selectedname =sourceclass = source<?php echo($ row ['source'] =='VAT')?'checked':''?> value =VAT> VAT 
< input type =radiong-model =selectedname =sourceclass =source<?php echo($ row ['source'] =='CST')?'checked':''?> value =CST> CST



jQuery

('keypress',function(e){
if(e.keyCode === 13)
{pre $('#gp_no')。
$(this).trigger(enterKey);
var val = $(this).val();
var dataString =gp_no =+ val;
$ .ajax({
type:POST,
url:post_process.php,
data:dataString,
dataType:'json',
成功:function(data){
$('。source').val(data.source);
}
});
}
});

post_process.php

  if(ISSET($ _ POST ['gp_no'])){

$ gp_no = $ con> real_escape_string($ _ POST ['gp_no']);

$ query =SELECT * FROM items WHERE items.gp_no = $ gp_no;
$ b $ if($ result = $ con> query($ query)){
$ row = $ result-> fetch_assoc();
$ source = $ row ['source'];
}
$ json = array($ vehicle_no,'source'=> $ source);
$ json = json_encode($ json);
echo $ json;


解决方案

所选单选按钮的值可以这样做:

  $('input [name =source]:checked' ).val()

当你从ajax调用得到响应时,检查你的按钮:首先改变它:

 < input type =radiong -model =selectedname =sourceclass =sourceid =VATvalue =VAT> VAT 
< input type =radiong-model =selectedname = sourceclass =sourceid =CSTvalue =CST> CST

$(#+ data.source).prop(checked,true)

您返回的值为 VAT CST


I've a radio button in my form and when I enter a reference number, I can fetch the corresponding form details along with source value using jQuery. I don't know how to set that value to radio button. Thank You!

<input type="radio" ng-model="selected" name="source" class="source" <?php echo ($row['source']=='VAT')?'checked':'' ?> value="VAT">VAT
<input type="radio" ng-model="selected" name="source" class="source" <?php echo ($row['source']=='CST')?'checked':'' ?> value="CST">CST

jQuery

$('#gp_no').on('keypress', function(e){
    if(e.keyCode === 13)
    {
        $(this).trigger("enterKey");
        var val = $(this).val();
        var dataString = "gp_no=" + val;
        $.ajax({
            type: "POST",
            url: "post_process.php",
            data: dataString,
            dataType: 'json',
            success: function(data){
                $('.source').val(data.source);
            }
        });
    }
}); 

post_process.php

if(ISSET($_POST['gp_no'])) {

    $gp_no = $con->real_escape_string($_POST['gp_no']);

    $query = "SELECT * FROM items WHERE items.gp_no = $gp_no";

    if ($result = $con->query($query)) {
        $row = $result->fetch_assoc();
        $source = $row['source'];
    }
    $json = array($vehicle_no, 'source' => $source);
    $json = json_encode($json);
    echo $json;
}

解决方案

If you are looking to get the value of a selected radio button you can do this:

$('input[name="source"]:checked').val()

When you get the response from your ajax call you check your button:

First change this:

<input type="radio" ng-model="selected" name="source" class="source" id="VAT" value="VAT">VAT
<input type="radio" ng-model="selected" name="source" class="source" id="CST" value="CST">CST

$("#"+data.source).prop("checked", true)

This assune that your returned value is VAT or CST
