WordPress From Bootstrap to WordPress Setup a Bootstrap Theme Add Bootstrap JS via the functions.php File

ie-emulation-modes-warning.js is not mentioned in this lesson

I'm guessing another script has been added to Bootstrap since this course was published. At the point of removing IE 9 scripts I have...

<!-- Just for debugging purposes. Don't actually copy these 2 lines! -->
<!--[if lt IE 9]><script src="../../assets/js/ie8-responsive-file-warning.js"></script><![endif]-->
<script src="../../assets/js/ie-emulation-modes-warning.js"></script>

There is no mention of the script outside the [if] statement, so not sure what I should do with it. For now I'm just adding it below where I hooked the other scripts, in functions.php, and commenting it out, until I know otherwise how to treat it.

UPDATE: In the footer I found ...

<!-- IE10 viewport hack for Surface/desktop Windows 8 bug -->
<script src="../../assets/js/ie10-viewport-bug-workaround.js"></script>

Same as above, I'm commenting it out in functions.php until I know what to do with it.

<?php


function theme_styles() {

    wp_enqueue_style( 'bootstrap_css', get_template_directory_uri() . '/css/bootstrap.min.css');
    wp_enqueue_style( 'main_css', get_template_directory_uri() . '/style.css' );

}
add_action( 'wp_enqueue_scripts', 'theme_styles' );

function theme_js() {

    global $wp_scripts;

    wp_register_script( 'html5_shiv', 'https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js', '', '', false );
    wp_register_script( 'respond_js', 'https://oss.maxcdn.com/respond/1.4.2/respond.min.js', '', '', false );
    wp_enqueue_script( 'ie_emulation', '/js/ie-emulation-modes-warning.js', '', '', false );
    wp_enqueue_script( 'ie_viewport', '/js/ie10-viewport-bug-workaround.js', '', '', false );

    $wp_scripts->add_data( 'html5_shiv', 'conditional', 'lt IE 9' );
    $wp_scripts->add_data( 'respond_js', 'conditional', 'lt IE 9' );
    $wp_scripts->add_data( 'ie_emulation', 'conditional', 'lt IE 9' );
    $wp_scripts->add_data( 'ie_viewport', 'conditional', 'IE 10' );

    wp_enqueue_script( 'bootstrap_js', get_template_directory_uri() . '/js/bootstrap.min.js', array('jquery'), '', true );

}

add_action( 'wp_enqueue_scripts', 'theme_js' );

?>

This is my functions.php file for the lesson after applying conditionals to the new .js files involving IE debugging/workarounds. The two javascript files are part of the local directory structure so they're wp_enqueue script, not wp_register_script. Then when adding their data, be sure your conditional is correct (Is it less than 'lt' IE 9, or is it IE10 specific?)

There are conditional statements you can use for this :)

I have the same question, but do not quite know what I should do - the link to the Github page confuses me as it is just outside my depth of understanding.

What exactly should I do with this line:

<script src="../../assets/js/ie-emulation-modes-warning.js"></script>

Also, what is the effect of completely deleting the line anyway?

I just and went ahead and added this code to the footer.php

<code> <!-- IE10 viewport hack for Surface/desktop Windows 8 bug --> <script> if (navigator.userAgent.match(/IEMobile\/10.0/)) { var msViewportStyle = document.createElement('style') msViewportStyle.appendChild( document.createTextNode( '@-ms-viewport{width:auto!important}' ) ) document.querySelector('head').appendChild(msViewportStyle) } </script>

</code>

Thanks Zac. I assumed they should be conditional but wasn't sure, since they are not conditional in the original Bootstrap files. So... conditional they shall be.

By the way, I really enjoy your courses. You're very thorough, easy to understand, and you make learning fun!

i made download of the archive - ie10-viewport-bug-workaround.js to the folder "JS". And added this: wp_enqueue_script( 'bootstrap_js', get_template_directory_uri() . '/js/ie10-viewport-bug-workaround.js', array('jquery'), '' , true);

is this right?
