I am new to Nodejs and having trouble when trying to export my js code which exists in HTML files to more js files for less redundancy in code (same js code in two HTML files):
I exported the js code from both HTML files to js a file (js_code_file.js for example) and tried using <script src="js_code_file.js" type="text/javascript"></script> in the header of the HTML file in order to import the file, and it did not work.
Is it because of Nodejs? and if it is - is there a way to "require" these files somehow?
<script src="js_code_file.js" type="text/javascript"></script>
Looking at the src attribute, js_code_file.js has to be in the same path as the .html file referencing it; that is, it has to literally be in the same folder. So make sure that is the case, otherwise, update your question with any errors you might be receiving.

I have an AngularJS project and I want Webpack to handle the build process for me, I need Webpack to output JS files dynamically from the src folder into my HTML template, and output them like this:
<script src="source1.js"></script>
<script src="source2.js"></script>
<script src="source3.js"></script>
...
Is it possible to load files in specific order rather than getting them all in one big file?
I'm working on a simple project where I included a simple js file to fetch out a data from api on click of a button. It was working when I had HTML file and js file in same folder and used by simply clicking on index.html . Now i am using expressjs for same and written all the HTML code in index.ejs file. For some reason, the js file has stopped working. I have tried changing the paths and carefully defining the path, also kept the file in same folder as of ejs file but it does not seem to work. Any suggestions would be helpful. The lines I have included in ejs file as are as follows. Here the js file is in the js folder of public folder of the project
<script src="jquery-3.2.1.min.js"></script>
<script type="text/javascript" src="js/script.js"></script>
I got this problem resolved by adding the following path to jQuery src
"https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"
instead of
"jquery-3.2.1.min.js"
Let's say I have folder scripts with 10 javascript files and instead of doing this:
<script src="scripts/js1.js"></script>
<script src="scripts/js2.js"></script>
<script src="scripts/js3.js"></script>
<script src="scripts/js4.js"></script>
<script src="scripts/js5.js"></script>
//and so on...
I want to do this:
<script src="scripts/*"></script>
which load ALL files in scripts
How would I go about doing this?
Won't be as easy as that, here is what you are looking for:
How can I include all JavaScript files in a directory via JavaScript file?
What you try to achieve is cumbersome from the client side. You can achieve the same through server-side scripting before you load your html file. You can use a task runner tool like grunt, gulp etc. (or write a script) that will traverse your target directory, retrieve all the *.js file paths and append their script tags in your html file.
Another solution is to use a tool to concatenate all your js files in one bundle file and only load that file from your html file. There are plenty of tools out there to do that
I have created a new Rails 4 project and I am trying to load an external JavaScript file in my HTML file. I have placed the JavaScript file in the /assets/javascripts directory and included the file in my HTML file.
My HTML file:
<html>
<body>
<script src="/assets/hello.js"></script>
</body>
</html>
My JavaScript file:
document.write("test");
I do not see any errors in my web browser console when loading the website. I am pretty sure I put the JavaScript file in to correct directory but the file will not run. Does Rails require something for external JavaScript files to work properly?
I have also tried defining a method in the JavaScript file and calling it within a <script> tag but I get a "Uncaught ReferenceError: methodname is not defined".
You probably need to list 'assets/hello.js' in application.js. The Rails asset pipeline compiles all JavaScript into application.js based on the filepaths that it finds listed there.

So I figured out why Rails wasn't loading my JavaScript file. When I created the Rails project, it included .coffee scripts which can be used instead of JavaScript. For some reason by default, the .coffee script was being run instead of the JavaScript file that I created. After deleting the .coffee script, my JavaScript loads as expected.
I have one .js file named final.js which I copied as bundle resource I have a requirement like the html document which reads this js file should download at runtime and store it in documents directory. But the js file is not able to read by the html when I loaded it in webview, because of the path of .js file.
I tried with the solution like below, but not worked.
<script src ="./final.js"> </script>
And finally I tried to copy the hardcoded path of application bundle like below, now it worked. Finally I come to know that the path is not proper.
> <script src ="/Users/unknownUser/Library/Application Support/iPhone
> Simulator/7.0/Applications/025EF3B6-F2E6-4162-8921-839D7D98FF58/HTMLGetdataTestApp.app/final.js">
> </script>`
Can any one tell me that how a html file which is stored in documents directory can read a .js file which is stored in main bundle with the correct path instead of hardcoded like above.
The simple solution will be copying the final.js file to documents directory.
Copy the js file from bundle to the document directory (where the html page is located) and set the path as:
<script src ="final.js"> </script>
