The term "Ext" has not been recognized or defined

Currently, I am facing an issue while attempting to integrate a TinyMCE plugin with ExtJs. I found a helpful demo example at this link, which I followed closely.

However, my implementation is failing as I am receiving an error message stating "Ext is not defined" in Firebug. Despite using a newer version of Ext, I made sure to include both the necessary css and scripts:

<link href="scripts/extjs/resources/css/ext-all.css" rel="stylesheet" type="text/css" />
<script src="scripts/extjs/ext-all.js" type="text/javascript"></script>
<script src="scripts/miframe/miframe-min.js" type="text/javascript"></script>
<script src="scripts/tinymce/jscripts/tiny_mce/tiny_mce_src.js" type="text/javascript"></script>
<script src="scripts/ux/Ext.ux.TinyMCE.js" type="text/javascript"></script>

In Firebug, there are no issues with finding or including any of the scripts mentioned above.

Following that, I called the Ext function in the head section of my aspx document:

<script type="text/javascript">
    console.log("Ready...");
    Ext.onReady(function() {
        console.log("set...");
        Ext.get("cmdOpen").on("click", function() {
            console.log("GO");
            var dlg = new Ext.Window({

//etc
</script>

After checking the console logs, "Ready..." gets displayed successfully before the code encounters an error. The error indicates that "Ext is not defined" in ext-all.js(), miframe-min.js(), Ext.ux.TinyMCE.js(), and within the .aspx file (Default.aspx).

I have not made any modifications to the included files, all of which are official releases.
Could it be possible that I missed out on some crucial statement? Or maybe there are additional elements that need to be included? I am currently unsure about how to proceed.

Answer №1

Make sure to include the ext-base.js file before adding ext-all(-debug).js to avoid the "Ext is not defined error". It's important to follow the correct order of includes as outlined in this page for a successful setup:

Answer №2

Discover a useful Firefox extension called "jsview," which allows you to view the scripts and CSS files included on a webpage.

Upon visiting this link mentioned in your post and accessing the ExtJs file, you'll see that the provided example is based on version 2.1 of the code.

For more information on Ext.ux.TinyMCE v0.6, check out this blog post. It specifies the following requirements:

  • Firefox 2+, Opera 9+, MSIE 7
  • ExtJS 2.1
  • TinyMCE 3.1.0.1
  • Ext.ux.ManagedIframePanel

It's important to note that updating to newer versions of TinyMCE or ExtJs may introduce breaking changes that need to be addressed. Consider directly extracting files from the example for a reliable version.

If opting for ExtJs v3+, ensure you have the latest components:
1) Check out the maintained ux.ManagedIframe, which has been updated for ExtJS 3.x here
2) Dive into the ux.TinyMce thread for the latest version (likely 0.7b) and troubleshooting tips if needed.

Answer №3

To enable the functionality, simply transfer the lib folder to the exjts project folder within your eclipse workspace. Provide only relative paths for it to properly function.

Answer №4

Visit the ExtJs official website to ensure that you have downloaded and included all required files in the correct order. It is advisable not to use a newer version as it may cause errors in the code. Experiment with simpler examples and only focus on referencing the Ext components to check if they load correctly.
