    html - Why does my javascript only fire when the code is repeated? - Stack Overflow

    I'm having an issue where I can only get my code to fire if I repeat it. See the below example. While the code is nearly identical if I take either of the two scripts out the code doesn't function with just one, yet if I run both the script fires fine, but only one instead of two. give it a go.

    This works (but only one script fires):

    <script type="text/javascript">
var url = window.location.href + "";
document.write('<script type="application/javascript" src=";mik21=' + url + '"/>');
</script>

<script type="text/javascript">
var url = window.location.href + "";
document.write('<script type="application/javascript" src=";mik=' + url + '"/>');
</script>

    This does not work:

    <script type="text/javascript">
var url = window.location.href + "";
document.write('<script type="application/javascript" src=";mik21=' + url + '"/>');
</script>

    Or this:

    <script type="text/javascript">
var url = window.location.href + "";
document.write('<script type="application/javascript" src=";mik=' + url + '"/>');
</script>

    Does anyone have any ideas? this is definitely the weirdest thing I've seen in a while.

    Thanks,

    • 2 don't use document.write is my first hint, who knows why that's even still valid in browsers since about 2005 – Jaromanda X Commented Jul 3, 2015 at 9:24

    • 2 is there something like <script src="..." /> – Arun P Johny Commented Jul 3, 2015 at 9:25
    • 3 Try it with <script …></script>. script requires a closing tag. – Sebastian Simon Commented Jul 3, 2015 at 9:31
    • 1 the code you shared works.. check in developer tools – salahuddin Commented Jul 3, 2015 at 9:38

    The problem is that your script tag is broken. A <script> tag must be closed by </script>.
    Now here is what happens:

    Example 1

    <script>
  document.write('<script src="test.js"/>');
</script>

    Produces the following markup HTML:

    <script>
  document.write('<script src="test.js"/>');
</script>
<script src="test.js">
  </body>
  </html>

    In general, browsers do not execute a <script> block until they find the corresponding </script>. There is no explicit closing tag in the above example so the browser ignores the tag.

    Example 2

    <script>
  document.write('<script src="test.js"/>');
</script>
This HTML will be consumed
<script>
  document.write('<script src="test.js"/>');
</script>

    Produces the following output:

    <script>
  document.write('<script src="test.js"/>');
</script>
<script src="test.js">
  This HTML will be consumed
  <script>
  document.write('<script src="test.js"/>');
</script>

    Notice that the dynamically written script tag is not closed. The browser will match this tag with the second </script> in the markup; everything in-between (incorrectly) bees part of this tag.

    Solution

    When using document.write, make sure that you close <script> tags properly. But note that you cannot use </script> as-is inside JavaScript code since it signals end of script block. You can use the following trick:

    <script>
  document.write('<script src="test.js"><\/script>');
</script>

    I have just tested this:

    Consider the source

    data:application/javascript;base64,Y29uc29sZS5sb2coIlRlc3QiKTs=

    This points to the following code:

    console.log("Test");

    This snippet below generates

    <script src="data:application/javascript;base64,Y29uc29sZS5sb2coIlRlc3QiKTs="/>


    <div>A</div>
<script>
document.write('<script src="data:application/javascript;base64,Y29uc29sZS5sb2coIlRlc3QiKTs="/>');
</script>
<div>B</div>

    However, this snippet below generates

    <script src="data:application/javascript;base64,Y29uc29sZS5sb2coIlRlc3QiKTs="></script>


    <div>A</div>
<script>
document.write('<script src="data:application/javascript;base64,Y29uc29sZS5sb2coIlRlc3QiKTs="></'+'script>');
</script>
<div>B</div>

    The first snippet logs "Test" but doesn’t display “B” in the HTML. The second works properly. In the Real-time HTML Editor not even "Test" gets logged for the first one. The implication of that is that all the HTML below the <script/> (which is inserted as <script>) gets consumed as Salman A’s answer points out.

    This is because the only valid syntax for <script> tags is <script></script> and not <script/>.

    This works:

    <script type="text/javascript">
var url = window.location.href + "";
document.write('<script type="application/javascript" src="https://testdomain./mik21?add=2140535&mik21=' + url + '"></scr'+'ipt>');
document.close();
</script>

    To prevent js from crashing, i've split the <script> tag into two strings.
