[英]Sending back multiple results from PHP via AJAX
i have setup some ajax, which i am just testing now, pretty much the idea behind it is to send some data from dropdown boxes to a php script, do some calculations and then return the result, it does it well and returns the result, but now rather than just sending back one result and outputting that, i want to send back multiple results and output them, i am able to send multiple data to the php script, so i am sure i can send multiple back. 我已经设置了一些ajax,我现在正在测试,其背后的想法是将一些数据从下拉框发送到php脚本,做一些计算然后返回结果,它做得很好并返回结果,但现在,而不是只发回一个结果并输出,我想发回多个结果并输出它们,我能够发送多个数据到PHP脚本,所以我相信我可以发回多个。
Anyway it only sends the first result back and not the rest. 无论如何,它只发送第一个结果而不是其余的结果。
Here is the AJAX 这是AJAX
<script>
$("document").ready(function (){
$(".add_extension").change(function(){
var m = document.getElementById('meter_square');
var meter_square = m.options[m.selectedIndex].value;
var s = document.getElementById('story_height');
var story_height = s.options[s.selectedIndex].value;
$.ajax({
type: "GET",
url: "script.php",
data: { meter_square: meter_square, story_height: story_height },
dataType: "json",
statusCode: {
200: function (result, result2)
{
$("#expected_gain").html(result.value);
$("#house_price").html(result2.value2);
}
}
});
})
});
</script>
And here is the php script 这是PHP脚本
<?php
$meter_square = $_GET["meter_square"];
$story_height = $_GET["story_height"];
$result = $meter_square + $story_height;
$result2 = $meter_square * $story_height;
echo json_encode(array("value" => $result, "value2" => $result2));
?>
You can see that i have already tried to give it a go from what i thought might work, if you need any other code or want me to remove the code i added which doesn't work, then let me know. 您可以看到我已经尝试从我认为可能有用的东西,如果您需要任何其他代码或想要我删除我添加的无效的代码,然后让我知道。
Thanks for all and any help 感谢大家和任何帮助
You're only going to receive one response object: 您只会收到一个响应对象:
function (response) {
$("#expected_gain").html(response.value);
$("#house_price").html(response.value2);
}
Try this. 试试这个。 Think it will help.
认为这会有所帮助。 No need to use status codes if u gonna use only success case
如果您只使用成功案例,则无需使用状态代码
$.ajax({
type: "GET",
url: "script.php",
data: { meter_square: meter_square, story_height: story_height },
dataType: "json",
success: function(data){
$("#expected_gain").html(data.value);
$("#house_price").html(data.value2);
}
});
