推荐答案
将您的submit HTML代码更改为<input type="submit" value="Add Employees"></input>
Change your submit HTML code to <input type="submit" value="Add Employees"></input>
并使用我的javascript源
And use my javascript source
<script type="text/javascript">
$( "#form_employee" ).submit(function( event ) {
var data = $(this).serializeArray();
data.push(
{name: "job", value: "add_employee"}
);
data = JSON.stringify(data);
$.ajax({
type: "POST",
url: "jsOnChange.php", //Set-Your-URL-Here
data: data,
contentType: "application/json; charset=utf-8",
dataType: "json",
async: false,
error: function(e)
{
alert(JSON.stringify(e, null, 4));
},
success: function(strDrivers){
alert(JSON.stringify(strDrivers, null, 4));
}
});
});
</script>
在.php侦听器中
<?php
ini_set("allow_url_fopen", true);
$jsonStr = file_get_contents("php://input"); //read the HTTP body.
echo $jsonStr;
?>
