如何获取点击图像的名称并将其与php变量进行比较？

Question

Two images, placed by php:

echo "<img onclick='test()' src=\"/img/Sun.png."\">";
echo "<img onclick='test()' src=\"/img/Moon.png."\">";
$x = "Sun.png";

js:

function test(){
if (clicked_image_name == $x) ...do something

So, how to get the name of clicked image, and how to compare it with a php variable ?

Answer 1

Put the value of $x in a hidden field. You'd be able to take the value then from javascript
