使用jQuery .load()将参数传递给并调用php函数 [英] Using jQuery .load() to pass a parameter to and call a php function
问题描述
这是我拥有的jQuery .load函数.我想做的是使用jQuery传递的值运行php函数.我想我只是不明白如何将jQuery的值传递给服务器.我可能需要使用.get或.post吗?请告知.
This is the jQuery .load function I have. What I want to do is run the php function with a passed value from the jQuery. I think I just don't understand how to pass values with jQuery to the server. Do I perhaps need to use .get or .post? Please advise.
$(document).ready(function(){
$("#scotland").click(function() {
$("#Main").load('thumbs.php #Main', $path=./scotland);
});
});
jQuery脚本定位的
php div.
php div that the jQuery script targets.
<div id="main">
<?php
function thumbnailload($path)
{
$dir_handle = @opendir($path) or die("Unable to open folder");
while (false !== ($file = readdir($dir_handle))) {
if(ereg("(.*)\.(jpg|bmp|jpeg|png|gif)", $file)){
echo "<a href='$path/$file'><img class='thumbnail' src='$path/thumbs/thumb_$file' alt='$file'></a>";
}
}
closedir($dir_handle);
}
thumbnailload($path);
?>
</div>
推荐答案
这种问题通常很早，不知道如何与客户端语言(JavaScript)交互到服务器端(PHP) ).但是，我们走吧！
It is usually in early to have this kind of problem, not knowing how to interact with a client-side language (JavaScript) to a server-side (PHP). But let's go!
对于"thumbs.php"页面接收参数，您必须通过GET或POST发送数据.
For the page "thumbs.php" receives a parameter, you must send the data via GET or POST.
JavaScript:
Javascript:
$(document).ready(function(){
$("#scotland").click(function() {
$("#Main").load('thumbs.php', {'path': 'scotland'});
});
});
thumbs.php
thumbs.php
<div id="main">
<?php
if(!empty($_REQUEST['path'])) { // i used $_REQUEST because it receives the data from POST or GET.
$path = $_REQUEST['path'];
$dir_handle = @opendir($path) or die("Unable to open folder");
while (false !== ($file = readdir($dir_handle))) {
if(ereg("(.*)\.(jpg|bmp|jpeg|png|gif)", $file)) {
echo "<a href='$path/$file'><img class='thumbnail' src='$path/thumbs/thumb_$file' alt='$file'></a>";
}
}
closedir($dir_handle);
}
?>
</div>
如果未传递数据，则jquery中的.load()方法使用GET请求类型.在我们的例子中，我正在传递数据({'path':'scotland'})，因此请求的类型为POST.
The method .load() in jquery uses a GET request type if the data is not passed. In our case, I am passing data ( {'path': 'scotland'} ), so the request is of type POST.
