Question

这部法典:

<input type="text" id="participant1"  name="name[1][]" value="Andi"/> </p>
<input type="text" id="idparticipant1" name="idparticipant[1][]" value="1001"/>

<input type="text" id="participant2"  name="name[2][]" value="Smith"/> </p>
<input type="text" id="idparticipant2" name="idparticipant[2][]" value="1005" />

      $.ajax({
  type: "POST",

  data: "nameparticipant=" + txt,
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  success: function(data)
  {
     $(this).next().val(data.d);
     //alert(data.d); 
  }
  //failure: failerEvent
});
});//keyup

 });
 </script>

蓝皮。 php

<?php
$nameparticipant=$_POST["nameparticipant"]);
$res = mysql_query("select * from table where upper(name) like  $nameparticipant% ");
$t=mysql_fetch_array($res);

echo"$t[nik]";
?>

除“安道尔”外,如果是参与者的关键投入名称,那么价值就变了0。而当它再一次回头来时,它的价值就改变了。

可以做些什么?

用途

var txt = $(this).val();

instead of

var txt=$(  [id^="participant"]  ).val();

remove unneccesory <p> tags from the code,

<input type="text" id="participant1"  name="name[1][]" value="Andi"/>
<input type="text" id="idparticipant1" name="idparticipant[1][]" value="1001"/>

<input type="text" id="participant2"  name="name[2][]" value="Smith"/> 
<input type="text" id="idparticipant2" name="idparticipant[2][]" value="1005" />

JavaScript,

$.ajax({
    type: "POST",
    url: "blue.php",
    data: "nameparticipant=" + txt,
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function(data)
         {
            $(this).next().val(data.d); 
         }
});
