javascript - My image with a PHP variable source is broken -


my end goal have image swaps different image when window scrolls past point. started javascript whole scroll position , set if/else statement.

<script type="text/javascript">     function checkheight() {         currentscrollpos = window.scrolly;          if (currentscrollpos < 325)             document.getelementbyid('test1').innerhtml = "../wp-content/uploads/2017/04/logo-1.png";         else if (currentscrollpos > 325)             document.getelementbyid('test1').innerhtml = "../wp-content/uploads/2017/04/logo-1-alt.png";     } </script>  <p id="test1"></p>

all of worked flawlessly. inner html contents of <p id="test1"></p> displayed correct image source , swapped said source when scrolled. perfect.

finally, went place image source actual source of <img> , that's hit wall. tried use simple php variable.

<?php $src = <<<end <p id="test1"></p> end; ?>

and worked. echo $src , displayed image source correctly before. proceeded, , put following code.

<img src='<?php echo $src; ?>' />

but nothing. seems works extent except it's showing me broken image symbol when load page. why not finding image files? missing stupid?

the new, working code. sorry wasting of time , being complete moron.

<script type="text/javascript">  function checkheight() {     currentscrollpos = window.scrolly;      if (currentscrollpos < 325)         document.getelementbyid('image').src = "../wp-content/uploads/2017/04/logo-1.png";     else if (currentscrollpos > 325)         document.getelementbyid('image').src = "../wp-content/uploads/2017/04/logo-1-alt.png"; } </script>  <body onload="checkheight();" onscroll="checkheight();"></body>     <img id="image" width="200px" />
