Powerful JQuery Find And Replace Text Techniques
- by admintech
The replace() method, which is included in the jQuery library, may be used to modify elements that have been specified by the user. Each element consists of a matched group of elements that will receive new information. It also returns only the removed items as well as all other non-removed components. jquery find and replace text is a very simple task that can be done by anyone who knows how jquery works.
Jquery Find And Replace Text On Page – The HTML:
In this example, we have an HTML paragraph with the ID attribute set to “mypara”. You will then notice a jquery script block in which we select the element “#mypara” using its ID tag. This code looks for any item within our document matching ID = mypara and replaces it with another identifier called newtext. After being replaced, both elements are returned from jquery search and replace text, so you can see what was changed or added.
You can use the jQuery replace() function to modify a certain string from a sentence. If you want to change or remove a particular word from a phrase, use the replace function. We’ll start by targeting that element where we want to make changes, then executing the replace() method with the targeted element and text as parameters. It simply replaces only the first instance of the term in the sentence. When you execute the replace() method, it looks for matchable text in the sentence and stops when it finds it.
You can use the replaceAll() method to replace all the instances of a string. We’ll go over it later in the examples. The syntax is almost the same as replace(), we’re just adding a parameter, and it works in exactly the same way.
You can also use functions like find() and filter().
filter jquery example: If you want to remove all instances of an element from within another element, this function comes in very handy. This code will hide every instance of the targeted word “jQuery” on our page using jQuery’s .hide() method (which simply hides any HTML elements matched by CSS selectors). You could achieve the exact same result with something like document.getElementsByTagName(‘*’).find(target_word) and then calling .removeChild for each one that was found however filtering would be much faster.
This jquery find and replace function can be used in some jquery plugins like jQuerify.
