Modify CSS class if user is using Internet Explorer version 10 or above

I am attempting to modify the CSS of 2 ASP controls using jQuery specifically for users accessing the site with Internet Explorer 10 or 11. This adjustment is necessary because IE10 onwards, conditional comments are no longer supported. My approach to achieving this is as follows:

<script>
    $(document).ready(function () {         
        if ($.browser.msie && $.browser.version === 10 || $.browser.msie && $.browser.version === 11) {

            alert('testIf');

            $("#txtUsername").removeAttr('loginInput');
            $("#txtPassword").removeAttr('loginInput');

            $("#txtUsername").css({
                "width": "284px",
                "border": "0px",
                "border-top": "1px solid #646464",
                "border-bottom": "0px #646464 solid",
                "border-left": "solid #646464 4px",
                "height": "33px",
                "background-image": "url(./Images/login-icon.png)",
                "background-repeat": "no-repeat",
                "padding-left": "16px",
                "float": "left",
                "display": "block",
            });

            $("#txtPassword").css({
                "width": "284px",
                "border": "0px",
                "border-top": "1px solid #646464",
                "border-bottom": "0px #646464 solid",
                "border-left": "solid #646464 4px",
                "height": "33px",
                "background-image": "url(./Images/login-icon.png)",
                "background-repeat": "no-repeat",
                "padding-left": "16px",
                "float": "left",
                "display": "block",
            });
        } else {
            alert('testElse');
        }
    });
</script>

I have implemented 2 textboxes like so:

        <asp:TextBox CssClass="loginInput loginUsername" TabIndex="1" ID="txtUsername" autocomplete="off" AutoCompleteType="Disabled" runat="server"></asp:TextBox>

        <asp:TextBox CssClass="loginInput loginPassword" TabIndex="2" ID="txtPassword" textmode="Password" runat="server"></asp:TextBox>

This is my modified CSS (with width being the only change from the original):

.loginInput {
    width: 285px;
    border: 0px;
    border-top: 1px solid #646464;
    border-bottom: 0px #646464 solid;
    border-left: solid #646464 4px;
    height: 33px;
    background-image: url(./Images/login-icon.png);
    background-repeat: no-repeat;
    padding-left: 16px;
    float:left;
    display:block;
}

.loginUsername {
    margin-top: 15px;
    background-position: 271px 9px;
}

.loginPassword {
    background-position: 271px -75px;
}

In Internet Explorer, the only necessary modification is altering the width for the CSS to display correctly. I've attempted moving the JS outside the document ready function but to no avail. Could someone provide guidance on what I might be doing incorrectly and suggest a way forward.

Answer №1

The issue lies in your browser detection code. When running the code in a JSFiddle, you will consistently end up in the else block, even when using Internet Explorer 11.

As suggested by Archer, consider detecting the browser on the server side and serving different CSS to the client.

Additionally, why are you using this:

 $.browser.msie && $.browser.version === 10 || $.browser.msie && $.browser.version === 11

Instead, try using this:

$.browser.msie && $.browser.version > 9

Discover Conditionizr, a tool specially designed for managing environment detects. It provides an Object that allows you to easily handle your tests. Take a look at the IE10 detect. Keep in mind that we're utilizing UA sniffing to disregard the Mobile version of IE10, as targeting Mobile IE requires different considerations due to their differences. Also, take a look at the IE11 detect.

conditionizr.add('ie10', [], function () {
  var version = false;
  /*@cc_on
    if (/^10/.test(@_jscript_version) && /MSIE 10\.0(?!.*IEMobile)/i.test(navigator.userAgent))
    version = true
  @*/
  return version;
});

You can use it to add a class like this (note ['class']):

conditionizr.add('ie10', ['class'], function () {
  var version = false;
  /*@cc_on
    if (/^10/.test(@_jscript_version) && /MSIE 10\.0(?!.*IEMobile)/i.test(navigator.userAgent))
    version = true
  @*/
  return version;
});

This also gives you complete Object access for inline JavaScript development:

if (conditionizr.ie10) {
  // Handle IE10 scenarios...
}

Furthermore, you can run callbacks with ease:

conditionizr.on('ie10'[, callback]);

To identify this issue without resorting to conditional comments or User Agent sniffing, you can utilize conditional compilation:

<script type="text/javascript">
    var isIE10 = false;
    /*@cc_on
        if (/^10/.test(@_jscript_version)) {
            isIE10 = true;
        }
    @*/
    console.log(isIE10);
</script>

Once the above code is executed, you can check for Internet Explorer 10 at any point:

if (isIE10) {
    // Code specific to Internet Explorer 10
}

For further information, refer to: How can I detect IE10 from JS when browser mode is IE9?

Update:

function isIE () {
var myNav = navigator.userAgent.toLowerCase();
return (myNav.indexOf('msie') != -1) ? parseInt(myNav.split('msie')[1]) : false;
}

Example:

if (isIE () == 8) {
 // Action for IE8
} else {
 // Handle other versions of IE or non-IE browsers
}

or

if (isIE () < 9) {
 // Handling IE versions below 9
} else {
 // Dealing with IE 9 and newer versions or non-IE browsers
}

or

if (isIE()) {
 // In case of IE
} else {
 // For other web browsers
}
