我们如何根据Java脚本If-else条件调用Php函数？ [英] How can we call Php functions based on the Java script If-else condition?

问题描述

如何在JavaScript If-else条件下调用Php函数。

How can we call Php functions with in the JavaScript If-else condition.

例如，

 if (top == self) {

  // not in any kind of frame

} else {

// in a frame

// calling php function

}
</script>

这里，PHP exit（）函数调用if和else条件。我需要仅在其他部分调用该函数。

Here, PHP exit() function calling for both if and else conditions. I need to call that function for only in else part.

请告诉我。

谢谢。

推荐答案

技术上不可行。但是，您可以对PHP页面进行AJAX调用并获取它返回的值。

Technically not possible. However you can make an AJAX call to a PHP page and get the values returned by it.

PHP（test.php）：

PHP (test.php):

<?php
$x = 10;
$y = 20;
$val = $y / $x;

echo $val;
?>

Javascript（ jQuery ）：

Javascript (jQuery):

$(document).ready(function() {
   $.ajax({url: 'test.php',
      type: 'POST',
      success: function(data){
         //takes the value returned by test.php and
         //puts it directly into the element with 
         //id = someElement
         $('#someElement').html(data);
      }
});

至于调用 exit（）; 并制作保存JavaScript停止处理的页面，除非你在PHP中控制同一页面上的逻辑并从那里调用 exit（）; ，否则你不能这样做。

As far as calling exit(); and making the page that holds the JavaScript stop processing, you just can't unless you control the logic on that same page in PHP and call exit(); from there.
