PHP和JS结合[关闭]

Question

I'm trying out this code, it's on WordPress in a loop:

<script type="text/javascript">
var ID = <?php the_ID(); ?>;
jQuery('#'document.write(ID);' a').click(function () {
    jQuery('#info-'document.write(ID);'').slideToggle('fast', function () {});
});
</script>

It's inside a HTML and it just keeps throwing errors, any idea what I'm doing wrong?

Example:

<script type="text/javascript">
var ID = 1;
jQuery('#1 a').click(function () {
    jQuery('#info-1').slideToggle('fast', function () {});
});
</script>

Answer 1

You missed the quotes arround the "the_ID()", but if the ID is an integer it is ok. Also you had two document.write() where they should not be.

<script type="text/javascript">
var ID = '<?php the_ID(); ?>';
jQuery('#'+ID+' a').click(function () { 
    jQuery('#info-' + ID).slideToggle('fast', function () {});
});

</script>
