You can actually use various other options if you want to add the script only in specific conditions such as:.
If you prefer to watch a video on YouTube on how to do this, this short video is quite a good one, on how to add Javascript to a single page:. We have detailed instructions on the page, so once you've seen the video, you can use this article as your reference. If you need to add the file to all pages, keep on scrolling to find other alternatives to this method below.
Once you reload the page, you'll find that the file has been added. You can confirm this by clicking on View Source of the page. If instead of adding the Javascript file to a page, you want to add it to a single page, we can use a slight tweak of this function, to make it apply to a single post.
You can use any variation of the following:. If you have the post title, you can use this, instead of the parameter "17". As we have seen, the easiest and cleanest method to add a javascript file to your WordPress theme is by using functions. In this case, instead of creating a condition to add the content to specific pages, we're going to add a generic function. Open your functions. Make sure you replace the template URL with yours before saving.
This plugin is a good option because it allows you to add any script without running any risk of breaking stuff. Moreover, you don't have to change or tweak any code yourself if you're not comfortable doing that , like we had to do in the previous example.
Changing code directly is typically a better option for web designers. The method using this plugin is easier. Instead of modifying the theme's files directly with the custom Javascript code, the plugin allows you to insert the code, which will then be added to the header or the footer of your site, depending on the options you've chosen.
You can download Insert Headers and Footers here. Use the location that matches best your specific needs using the following as an example.
The 2nd option you can use with this plugin, is the option to the add the code directly into WordPress without the need of using a specific file. This can be used when you are using a 3rd party service, such as Google Analytics, Drip, or another tool which needs some script added to your site. Just take the script and drop it into the Scripts in Header window:.
Reload the front-end, and check your website's source to make sure that the code is now showing. It's also a good idea to browse a few pages to confirm that everything is still working well.

To use JavaScript repeatedly within your site, you can either set the call for the JavaScript, or the script itself, in the head of your header. To "load" the JavaScript file into your site, in the head , add something like this:.
In the spot where you wish to use the JavaScript, set the call for the JavaScript. For example, you are using a JavaScript that sets a link for users to "email this page" to a friend and you want it to be under the post title. It might look like this:. To use JavaScript inside of posts in WordPress, you need to take a few more steps. Odds are that this usage is for one or only a few instances, so adding the script to the header would only add code you don't need to your header.
For the occassional or one time use of JavaScript, you need to put the script into a JavaScript file and then call it out from within the post. Make sure that each script is defined by its function name such as:. To include a JavaScript inside a post, you need to combine both the call to the script file with the call to the JavaScript itself.
You might have a collection of scripts that you call from time to time, like a scripts which calculate time zones or distance, or maybe scripts that create some effect or accent on your page. You likely could but if you have an SEO plugin you are currently using you would want to check with that plugin to see if the plugin does that already.
A well-presented roundup of the better-known options for what is becoming a common need. However, many WordPress users are not and do not want to be programmers.
You can put them in any component, though I prefer. All you need then is something that can compile and run the script. However, as a JavaScript programmer myself, I was able to write one and put it in the library as EasyCoder. The scripts resemble English, have about the same complexity as SQL and can do most of the things commonly required to manage content and interactivity in a web page. EasyCoder is also fully pluggable so other programmers can add modules themselves.
