检索Ajax调用多个值 [英] retrieve multiple values from ajax call

问题描述

所以，我要送经jquery.ajax数据PHP是返回一个值（即整个PHP页面，该页面只发送一个值）

So I'm sending data via jquery.ajax to php which is returning a one value (i.e. the entire php page which only sends one value)

我想从PHP页面中弹出两个值，但我怎么能与jQuery分裂两个值吗？

I'd like to pull two values from that php page but how can I split the two values up with jquery?

我想要实现的是，

1. 在按钮，点击发送列表项的信息和IDS
2. 在jQuery使用AJAX发送到PHP的每个项目
3. PHP的取值，并将其保存到数据库中，然后吐出了一个新的ID
4. 在jQuery的保存新的ID列表项，这是previously附着。

这是我遇到，我不能让jQuery来针对老列表项的问题。由于我使用一个for循环，其结果是在函数中我永远只能针对最后一个列表项目。

The problem that I'm running into that I can't get jquery to target the old list item. Since I'm using a for loop and the results are inside of a function I can only ever target the last list item.

这里的code有问题，我认为会的工作，但事实并非如此。

Here's the code in question, which I thought would have worked, but it didn't.

var i;
  for (i = 0; i < updatearray.length; ++i) {
    var curval    = updatearray[i],
        rowid     = "#row_"+curval,
        text1val  = $(rowid+" .text1").val(),
        text2val  = $(rowid+" .text2").val(),
        text3val  = $(rowid+" .text3").val();
        cardorder = $(".edit_main li:visible").index($(rowid)) + 1;

    $.ajax({
      type: "POST",
      url: "../../study/edit/save.php",
      data: { prowid: curval, ptext1val: text1val, ptext2val: text2val, ptext3val: text3val, pdeckid: deckid, pcardorder: cardorder }
    })
    .done(function( msg ) {
      $("#row_"+curval+' button').val(msg);

      alert("Data Saved2: " + msg );
    });  
  }

由于某些原因，CURVAL变量总是最后一个到数组中。因此，要解决这个问题，我可以通过PHP发送正确的行，但我不知道如何把它们分开。所以我希望它看起来像这样的基本。

For some reason the "curval" variable will always be the last one in the array. So, to counter this, I could send the correct row via php, but I don't know how to split them up. So I'd want it to look like this basically.

 .done(function( newValue, oldValue ) {

   $("#row_"+oldValue+' button').val(newValue);
 });

如果我想要做的是目前还不清楚，请说出来，我会尽力提供更详尽的解释。

If what I'm trying to do is unclear please say so and I'll try to give a more thorough explanation.

推荐答案

您可以得到超过2值超出你的PHP的，还有一些方法，我觉得最流行的，虽然是使用JSON。

you can get more than 2 values out of your php, there are some ways, i think the most popular though is with JSON.

让说在你的PHP：

$arr = array(
 "value_1"=>46534,
 "value_2"=>654
);

echo json_encode($arr);

您将得到JSON对象：

you will get the JSON object:

{"value_1":46534,"value_2":"654"}

和比你可以使用它像这样在你的诺言

and than you can use it like this in your promise

$.ajax(...).success(function(data){
    var value1 = data.value_1;
    var value2 = data.value_2;
})
