是否可以在javascript中传递php变量？

Question

I am trying to pass a php variable inside javascript bt it is not working.

<a href="javascript:wait1();getPass('<?php echo $current?>');">Comment</a>

Is it possible to do so or I may be incorrect somewhere...

Thanks for your response in advance! :)

Answer 1

You're dynamically generating Javascript. You will save yourself some headaches if when you need to do this you, keep it simple. Transfer the data from PHP to Javascript in the simplest way possible at the top of the page:

<script type="text/javascript" >
var $current = '<%? echo $current; %>';
</script>

As others have pointed out, you will want to encode and quote your php variable, using json_encode (in which case you probably won't need the quotes), or a simpler escape function if you know the possible values.

Now, your inline code can be simpler:

<a href="javascript:wait1();getPass($current);">Comment</a>

A final recommendation would be to pull this out into its own function, and use the "onclick" attribute.
