Replace text for every first child for multiple items

nth first-child
css second child
css nth-of-class
css every nth-child
nth-of-type
css not(:first-child)
scss first-child
css last-child

Two identical select boxes

<select class="select">
  <option>- OPTION -</option>
  <option>1</option>
  <option>1</option>
</select>

<select class="select">
  <option>- OPTION -</option>
  <option>1</option>
  <option>1</option>
</select>

Replace - OPTION - with - SELECT -

$(".select option:first").text("- SELECT -");

Code above replaces only first select box, ignores the second. Why? How to apply to all/any?

:first will only select the first element of all the options combined together.

:first-child will select all elements that are the first child of their parent.

$(".select option:first-child").text("- SELECT -");

UPDATE regarding speed

Below, user @kosmos suggested using .find(). This method is much less performant than using :first-child. Some developers usually don't think twice about performance because it's still really quick but these can add up. Now you know that faster ways exist to achieve the same result so I would suggest using this knowledge.

This is the test case I set up to confirm: http://jsperf.com/find-versus-first-child

jQuery in easy steps: Create dynamic web pages, Child selector All child elements of a specified parent element can be selected using a “Child” selector stating the parent name followed by a “>” character and the For example, a selector $(“li:first-child”) selects the first child list item element “document ready” event by selecting a list item element and replacing its text  The replaceChild() method replaces a child node with a new node. The new node could be an existing node in the document, or you can create a new node. Tip: Use the removeChild() method to remove a child node from an element.

Though the other answers are valid, you could also type

$(".select").find("option:first").text("- SELECT -");

to get all .select elements and, for each one, get the first option child.

:nth-child, The :nth-child selector allows you to select one or more elements based on Select the first list item */ li:nth-child(1) { } /* Select the 5th list item text-align: center; have to do the math yourself—there are several :nth-child testers and Region dimension can change its position in the table when the user  To select multiple carets, click or make first text selection as usual, and then press Alt while you click or select text in each additional location. You can also automatically add matching text as additional selections, or select a box of text to edit identically on each line.

you can try with below code

$(".select option:first-child").text("- SELECT -");

:first-of-type, The :first-of-type selector in CSS allows you to target the first occurence of an Suppose we have an article with a title and several paragraphs: happen because the paragraph is not the first child of its parent (the <article> ). Want to tell us something privately, like pointing out a typo or stuff like that? old_text is the cell containing the text you want to replace. start_num tells Excels where the text you want to replace starts within the cell. num_chars is the number of characters you want to replace. new_text is the text you’d like to replace that number of characters. Keep in mind that new_text does not need to be the same length as num_chars. You could tell Excel to replace “K” with “Kasper,” and it would work.

:first-child, The :first-child CSS pseudo-class represents the first element among a group of sibling elements. p> </div> <div> <h2>This text isn't selected: it's not a `p`. <​ul> <li>Item 1</li> <li>Item 2</li> <li>Item 3 <ul> <li>Item 3.1</li> <li>Item 3.2</li> <li>Item 3.3</li> </ul> </li> </ul> Recommendation, No change. If you are tired of find and replace the values time and time again, the following VBA code can help you to replace multiple values with your needed texts at once. 1. Please create your conditions that you want to use which contain the original values and new values. See screenshot: 2.

But due to the recursive nature of the List.Generate-function, this result is not safe. So when Text.Replace kicks in on: Replace “air” with “water”, searching again also for substrings, a part of “ch air ” with be replaced by water: “ch water “.

HTML DOM replaceChild Method, Replace the first child node of <ul> with the newly created text node item.​replaceChild(textnode, item.childNodes[0]); // Note: This example replaces only the Text  Deployment Software and System Administrator Tools. It can be very time-consuming and tedious to sift through many files. Unless you’re a fan of working over a weekend and opening file after file while being slumped in a chair, then I would suggest making use of the information from today’s PowerShell blog post!

  • Was thinking of this. Will be nice if you elaborate why find works here? Because if you use children then it won't work.
  • Although this is true, performance wise using :first-child is almost 3x faster than running a query like .find(). Check out this test I made and run the test: jsperf.com/find-versus-first-child
  • @BhojendraRauniyar I don't know if it's clearly stated in the docs, but when using $elem.children(selector), jquery will first create a set of all children, then filter using the selector. So in your case the first option of the set will be returned. When using .find, it's different. jquery will first initalize with 2 subsets of .select, then loop over each of them to apply the find function using the selector
  • @Logar Thanks for the explanation.
