Javascript && doesn't work in Wordpress posts. I know it is better not to write Javascript in posts, but makes sense in this case. I think there are plugins that could make this work, but got to be a simpler way... I could avoid using AND in my code logic, but that would be a pain.
I've heard that \u0026 could do it, but can't get that to work for me. I've also heard that would work, but that doesn't work for me either. So I've done my research, but none of the solutions I've come across work.
Any other suggestions?
Thanks,
Sam
Javascript support in every page.If you want to apply javascript in single.php file.
you can put end of file using <script> // code </script>
But make sure your php tag is complete or not before start script tag.

I've been trying to use excel-builder.js library to generate and Excel file and download it automatically, just as done here.
Now, I must stress out that I'm rather new to front end development, otherwise I might have figured it out already...
Anyway, what I can't seem to figure out is what is this "downloader" in the example? download is required and downloader is used like magic, but for me it doesn't work (since I don't really know what to require).
Has anyone tried it successfully? Thanks in advance!
OK, sorry for the bother. As I stated, I'm new to this.
I found the relevant code, and like in other places, it has to do with creating an invisible form and submitting it.
My problem is quite generic: I know that I have a JavaScript issue somewhere. Now I don't know how to start searching where the problem could be. Usually I use the Firefox built-in or the Firebug Debugger. I know how to use it in general. But what I don't know is where to start. Where should I set breakpoints? I often have this kind of problem.
As an example which is my current problem: I have a page with an unordered list. Every second list item is empty for some reason. I can see that the page gets loaded with proper list items. But then some JavaScript seems to add those empty items. It's a Yii application that inserts some JavaScript directly into the HTML but let the browser also load jquery.js, bootstrap.js and yii.js. I haven't added any own JavaScript.
Now, as I said, I don't know where to start to find the problem. It might be that I have done something wrong with some configuration. But it could also be bug. I just want to figure it out somehow.
With my current issue, the best would be to have a breakpoint on a function like onInsertEmptyListItemToCounfuseDeveloper() ...
I don't want a solution to my current issue. I'd like to know in general, where and how to start finding JavaScript related problems. Especially, with third-party JS. With some applications (CMS, shops,...) there are sometimes a lot of JS files. This makes it more worser.
I hope this question is answerable and you can provide some experiences.
Not speaking 'bout the CMS right now, but in general my method is
1) If you did not add any of your onw scripts, just 3rd party, delete them all of your project e.g.
You've added jquery.js, bootstrap.js, yii.js so you remove them and then you test if all works fine, if so, add first one, for me it would've been jquery.js, test again, if no bug visible add second and so on. In this case you'll see in which file is some bug or sort of unexpected behaviour.
2) Here is the worst part, in the found file you should find the problem part. So, download the full version, not production, open it in editor, and start searching... The good news are that you don't have to look through all file, just find the event listeners in your devtolls or firebug and follow them.
All of this is just my experience , so if someone know better methods, I would like to hear 'em too.
It would depend on the code. Generally, if I have a function that is suspicious, I put breakpoints or console.log() at the beginning and end of the function and see if both are executed. Then I follow the logic down to figure out which piece is broken. It really depends on the code though.
I'm working with a client that has a view that, after a user logs in, this view loads a template, that dynamically draws a canvas with jQuery, and generates an image copy of the canvas.
They want to protect the jQuery code, hiding the process in the python code.
I tried using PyExecJS, but it doesn't support jQuery, since there is no DOM.
I've also tried urllib2, mechanize and Selenium, but none worked.
Is there an alternative or have I missed something?
Update/Resolution: In case someone stumbles onto this question: I ended up using Selenium for Python to load the JS function, fed it the necessary data and extracted the image from it. It has a bit of an overhead, but since the main goal was to keep the JS code obfuscated, it worked.
If I understand correctly, you are trying to hide jquery code.
You can't hide jquery code from the user, because django processes python code before it serves up the template, there's no way to protect jquery code with python. Really the best thing you can do is to minimize and obfuscate the code, but that only makes it difficult for human reading.
I'm stuck with a python problem, look.
I have to scrap a page that has JS functions, but that's not the real problem, the real problem is that the information I need is provided by the function.. So I need to run the function to make sure it'll build the HTML code that I need, and then work on it to get what I want..
Just to make sure i'm clear, the JS function build the HTML code, but when I scrap it, it doesn't get HTML buid, it just return the JS function...
I am using mechanize and beautifulSoup for the scraping process.. does anyone know what do I have to do to emulate the JS function to get the HTML code that I need?
Thanks in advance.
You need a scrapping framework that supports javascript. Selenium is one of them and I got good results using along with BeautifulSoup.
You may want to check PyVirtualDisplay if you are going to use Selenium with Mozilla Firefox.
Well I had lots of scripts so what I did is that I combined all of them into one script file, which contains files like Jquery library too.
But now the problem is that it has stopped working, I don't know why did this happen.
What I did is that I took every script copied and pasted it and then I gave some space under it by pressing enter a few times and then I used to paste other script, I was told this was the method to combine scripts but now the scripts don't work.
Here is the link to combined scripts http://files.cryoffalcon.com/bloghuts/uncompressed/BlogHuts%20UNCOMPRESSED.js
And the link to a live example is http://bloghutsbeta.blogspot.com/
ANSWER/SOLUTION:
Earlier I was using an older version of Jquery I think 1.5 now I changed it to latest 1.7 and that was the reason that everything stopped working. It had nothing to do with combination. I am using all scripts combined and everything is working fine But why is older version better than New that is a new question for me
First, I'd suggest you move the jquery library links out to the main page. Have one file for all of your javascript, and include the other stuff on separate lines.
Whether or not you do that, though, your problem is almost certainly some sort of unclosed bracket or semicolon missing or something similar. Javascript often reacts to stuf like that by throwing its hands up in the air and giving up. The way to fix it is to go through your file and pick a function that is not currently working, but that is easy to test for functionality. Then comment out everything else, and test to see if the function works. If not, fix the function until it does work. Then, one piece at a time, uncomment each of the other blocks, again testing to see if the initial function works. If uncommenting a block causes the thing to stop working, then that's the block that you need to fix. Depending on how long your blocks are, you may need to do this in tiers
First, don't do that with jQuery, ever. You're almost always better off pointing your script src to a public CDN somewhere.
Second, what you're trying to do is very brittle, and probably not worth troubleshooting. If you have that many JS files, you really need to use a module library (I like require.js) to give your project some structure and make it more manageable. Most libraries like this will include some sort of utility to combine and minifi your scripts safely.
This will take some work on your part to get things setup, but it should prove well worth it in the long run!
