PHP语法中的JavaScript

Question

I think this is a simple problem of my not knowing my syntax very well yet, but I am trying to get a js variable in a PHP, which actually happens to be in another js. I keep getting unterminated string literal error amoungst others general not working errors.

Code is as follows taking out the unnecessary

<script>
        jQuery(document).ready(function() { 
                var caNumber = document.getElementById("doc_id").value;                         
                var uploader = new plupload.Uploader({
                    url: '<?php echo admin_url('admin-ajax.php?project='.$_GET["project"].'&action='.$_GET["action"].'&number=caNumber') ?>'
                 });};
</script>

The problem in question is how to get the CaNumber in the url: where I have show CaNumber.

Thank you for time and assistance.

You are merging both php and javascript. Keep them separate.

url: "<?php echo admin_url('admin-ajax.php?project='.$_GET["project"].'&action='.$_GET["action"].'&number= ')?>"+caNumber;
