Let's say I have three field machine names in Drupal on a content type in Drupal:

company_color_schema , company_logo , and company_some_picture

I would like to retrieve the company_color_schema which will give me a plain text hex color code using JavaScript so that I can use it for a div background color.

Is there a way to access these values using JavaScript? I've looked at available documentation, but none seems to cover it.

You should use drupalSettings for this.

You can attach them in hook_node_view or similar depending on your needs

Actually, you don't need javascript to set div background. The better way is to use hook_preprocess_HOOK:

mymodule_preprocess_node(&$vars) {
  $vars['background'] = $vars['node'][WHATEVER_VALUE];
}

Put this code into your module, clear caches and then you can use $background variable in your node.tpl.php

How to retrieve the GET query string parameters using Express, Let's see how to get the properties and their values. Retrieve the GET query string parameters using Express. The query string is the Download my free Express.js Handbook, and check out my premium Node.js Course. You can use reference of class CL_BSP_WD_MIXED_NODE to capture mixed node. Use method IF_BSP_WD_EXT_PROPERTY_ACCESS~GET_MODEL_NODE to get model node and its values. For value node attributes you can directly use IF_BOL_BO_PROPERTY_ACCESS methods.

One way you can do this is to place JavaScript code in a view template file, at least part of it. So let's say you have a JavaScript row like this:

<?php $value_you_get_from_php = ... ; ?>

    <script>
        var bcgColor = <?php echo $value_you_get_from_php; ?>;
    </script>

So you'll get your color field value from PHP and print it out inside inline JavaScript code, exactly at position where you defined your JavaScript variable value. Then you can use that JavaScript variable anywhere you need it.

Another way would be making an Ajax call with i.e. the node id as parameter, but the first option is easier, if it's acceptable.

Or, the easiest solution (inspired by Artreaktor's answer): Just shoot color directly from a template file - add the style tag attribute and set color from that. Artreaktor's solution may be more by rules, but mine is easier to implement.

Get Query Strings and Parameters in Express.js, In this article, I assume you have some experience with Node.js and creating The query parameters are the actual key-value pairs like page and limit with All we do is take the req object and retrieve our params from the params object. I have a problem going through an XML document (with C#) and get all the necessary values. I successfully go through all specified XmlNodeLists in the XML document, successfully get all XmlNode values inside, but I have to get some values outside of this XmlNodeList. For example:

How to access query string parameters, In Node.js, functionality to aid in the accessing of URL query string The url.​parse() method returns an object which have many key value pairs one of to access query string parameters is parsing them using the querystring  Retrieve the GET query string parameters using Express The query string is the part that comes after the URL path and starts with a question mark ('?'). Let's see how to get the properties and their values.

How to Get URL Parameters in Node.js, The get() method of URLSearchParams object gets the value of the given parameter. const url = require('url'); const current_url  Reading the contents of a file into memory is a very common programming task, and, as with many other things, the Node.js core API provides methods to make this trivial. There are a variety of file system methods, all contained in the fs module. The easiest way to read the entire contents of a file is with fs.readFile, as follows:

Node.js - Request Object, Node.js - Request Object - The req object represents the HTTP request and Contains key-value pairs of data submitted in the request body. req.get(field). By using nodes () and value () methods, you can accomplish this as shown in the following: SELECT nref.value (' (first-name/text ()) ', 'nvarchar (50)') FirstName, nref.value (' (last-name/text ()) ', 'nvarchar (50)') LastName FROM T CROSS APPLY xCol.nodes ('//author') AS R (nref) WHERE nref.exist ('first-name [. != "David"]') = 1

Object.values(), The Object.values() method returns an array of a given object's own enumerable property values, in the same order as that provided by a forin  Access a node using its index number in a node list. Use the getElementsByTagName () method to get the third <title> element in "books.xml". Loop through nodes using the length property. Use the length property to loop through all <title> elements in "books.xml". See the node type of an element.
