Question

Internet Explorer 9 encountered a JavaScript error: SCRIPT5007. It was unable to access the value of the property 'ui' because the object is null or undefined

My website is functioning properly on Chrome, Firefox, and Internet Explorer 8. However, when it comes to Internet Explorer 9, some strange errors occur just by hovering over elements.

SCRIPT5007: Unable to retrieve the value of the property 'ui': the object is null or undefined ScriptResource.axd?d=sTHNYcjtEdStW2Igkk0K4NaRiBDytPljgMCYpqxV5NEZ1IEtx3DRHufMFtEMwoh2L3771sigGlR2bqlOxaiwXVEvePerLDCL0hFHHUFdTOM0o55K0&t=ffffffffd37cb3a1, line 181 character 1914

When I follow the link to the error in the JavaScript, it points me to this code snippet:

onNodeOver:function(B,A){A.ui.onOver(B)},onNodeOut:function(B,A){A.ui.onOut(B)}

I'm unsure how to approach fixing this error. Although I came across this solution, it didn't resolve the issue for me.

Any thoughts or suggestions?

Answer 1

Answer №1

Several older JavaScript libraries struggle to function properly in IE9 due to differences in how it handles certain aspects compared to IE8.

Code that specifically targets IE may not work as expected in IE9 unless it is modified to accommodate this version of the browser.

Prior to updating the JS code, consider utilizing the "X-UA-Compatible" meta tag to ensure your webpage operates in IE8 mode.

EDIT: It's surprising to see continued interest and support for this topic, even with advancements to IE11. Most modern JS libraries now provide native compatibility with IE9 and many also support IE10. The need for the meta tag has diminished, but it is important to check compatibility, especially regarding cross-domain scripting and CDN-based library functions such as Dojo 1.9 vs. 1.9.1 on IE10.

EDIT 2: It is essential to update and modernize websites, particularly in mid-2014, to eliminate dependencies on outdated versions of Internet Explorer.

It seems that legacy code continues to persist, evident by ongoing upvotes well into 2016. Our coding legacies will likely endure long after our time.

Encountered the same problem with IE9. After following the solution provided above, I inserted the following line:

<meta http-equiv="X-UA-Compatible" content="IE=8;FF=3;OtherUA=4" />

into my <head> section and it resolved the issue.

Answer №3

My code is designed to detect IE4 or newer and is currently working flawlessly on websites for both my company's clients and my personal projects.

To implement this functionality, simply add the following constants and function variables into a JavaScript include file on your page...

//methods
var BrowserTypes = {
    Unknown: 0,
    FireFox: 1,
    Chrome: 2,
    Safari: 3,
    IE: 4,
    IE7: 5,
    IE8: 6,
    IE9: 7,
    IE10: 8,
    IE11: 8,
    IE12: 8
};

var Browser = function () {
    try {
        //declarations
        var type;
        var version;
        var sVersion;

        //processing
        switch (navigator.appName.toLowerCase()) {
            case "microsoft internet explorer":
                type = BrowserTypes.IE;
                sVersion = navigator.appVersion.substring(navigator.appVersion.indexOf('MSIE') + 5, navigator.appVersion.length);
                version = parseFloat(sVersion.split(";")[0]);
                switch (parseInt(version)) {
                    case 7:
                        type = BrowserTypes.IE7;
                        break;
                    case 8:
                        type = BrowserTypes.IE8;
                        break;
                    case 9:
                        type = BrowserTypes.IE9;
                        break;
                    case 10:
                        type = BrowserTypes.IE10;
                        break;
                    case 11:
                        type = BrowserTypes.IE11;
                        break;
                    case 12:
                        type = BrowserTypes.IE12;
                        break;
                }
                break;
            case "netscape":
                if (navigator.userAgent.toLowerCase().indexOf("chrome") > -1) { type = BrowserTypes.Chrome; }
                else { if (navigator.userAgent.toLowerCase().indexOf("firefox") > -1) { type = BrowserTypes.FireFox } };
                break;
            default:
                type = BrowserTypes.Unknown;
                break;
        }

        //returning result
        return type;
    } catch (ex) {
    }
};

After adding these functions, you can easily use conditional statements like...

e.g.

value = (Browser() >= BrowserTypes.IE) ? node.text : node.textContent;

or

WindowWidth = (((Browser() >= BrowserTypes.IE9) || (Browser() < BrowserTypes.IE)) ? window.innerWidth : document.documentElement.clientWidth);

or

sJSON = (Browser() >= BrowserTypes.IE) ? xmlElement.text : xmlElement.textContent;

Understand how it works? I hope this information proves useful to you.

Also, remember to test the Browser() function post-IE10 release to ensure compatibility with any rule changes they might introduce.

Dealing with a similar problem, I found the solution by adding authentication configuration in the web.config file. Previously, I had been using the code snippet on my .aspx page without it. Now that I have made the necessary changes, my code is running smoothly.
