问题描述
常规概述
大家好，我有4个跨度中值的动态输入但是对于这个问题的目的，我把一些价值。我想从跨度中获得的价值，使用Ajax的PHP文件发送给他们。如果他们满足的PHP文件，然后报警一些消息所设定的标准。这是我迄今为止..
Hi all, I have 4 spans in which values are inputted dynamically but for the purpose of this question i put in some values. I want to get the value from the spans, send them using ajax to a php file. If they meet the criteria set in the php file then the alert some message. This is what i have so far..
的HTML
这基本上包含了跨度及跨度内的一些数字，按钮下方有一个onclick事件来调用名为检查的JavaScript函数。
This basically contains the span and some numbers within the span, the button below has an onclick event to call a JavaScript function called check.
<span id="first" name="first">40</span>
<span id="second" name="second">50</span>
<span id="third" name="third">30</span>
<span id="fourth" name="fourth">40</span></center>
<input type="button" id="button" name="button" onClick="check()"/>
的JavaSript
此基本上存储每个跨度字段中指定的变量的值，然后尝试使用AJAX，然后它会提醒在检索成功消息，同为一个失败消息的消息发送这些变量
This basically stores the value of each span field in a specified variable then tries to send these variable using ajax, then it alerts a message in retrieving a success message and same for a failed message.
function check() {
var one = $('#first').val();
var two = $('#second').val();
var three = $('#third').val();
var four = $('#fourth').val();
$.post("test.php",{ data : "one"+"&two"+"&three"+"&four" } ,function(data)
{
if (data=="yay") //for no input
{ alert("yay");
}
else
{
alert("nay");
}
}
}
的PHP 这些都是条件跨度领域必须满足的值，则AJAX功能检索成功，从这里失败的信息。
The PHPThese are the conditions the values in the span fields have to meet, the ajax function retrieves the success and failed messages from here.
$one = $_POST["first"];
$two = $_POST["second"];
$three =$_POST["third"];
$four = $_POST["fourth"];
if($one > 5) {
echo "yay";
}
elseif($two > 10 ) {
echo "yay"; }
elseif($three > 15 ) {
echo "yay"; }
elseif($four > 20 ) {
echo "yay"; }
else{
echo "nay";
}
问题
在没有显得有点调试它确实是，PHP是得到任何值，这意味着该数据没有被正确传递。我不认为这是通过AJAX通过多个项目的方式。有谁知道我可以解决这一问题？在adance非常感谢。
After a bit of debugging it doesn't seem that the php is getting any value which means the data hasn't been passed properly. I don't think that's the way to pass multiple items through ajax. Does anyone know how i can fix this?Many Thanks in adance..
推荐答案
。员额 可以是参数映射到该请求一起发送：
The second argument of .post can be a map of parameters to send along with the request:
$.post("test.php", {
first: one,
second: two,
third: three,
fourth: four
}, function(data) {
//Done!
});
在地图上的按键（如第一，第二等）的名称与您会能够从你的PHP脚本访问的值。
The keys of the map (e.g. first, second etc.) are the names with which you'll be able to access the values from your PHP script.
