Element manipulation
The element manipulation methods allow you to treat a jQuery object as a single HTML element.
Reading methods will be applied to the first element.
Modification methods will be applied to all elements in the jQuery object and return jQuery object.
// builder pattern
var newDiv2 = $("<div>").html("div content")
.attr("id", "new")
.addClass("w-50")
.css({'border': '1px solid red', 'color':'blue'});
$("p").removeClass("myClass noClass")
.addClass("yourClass");
| methods | description |
|---|---|
| html() | Returns the HTML content of the first element. |
| html(str | func) | Sets the HTML content of each element. The func parameter is a function that returns new HTML content and has two arguments:
|
| text() | Returns content of the first element as text (i.e. without HTML tags). |
| text(str | func) | Sets the content of each element to the specified text. The func parameter is a function that returns new text and has two arguments:
|
| attr(attrName) | Returns the attribute value of the first element. To retrieve DOM properties such as the checked, selected, or disabled state of form elements, use the prop() method. |
| attr(attrName, val | func) | Sets one or more attributes of each element. The func parameter is a function that returns a new value and has two arguments:
|
| removeAttr(attrName) | Remove an attribute from each element. The attrName parameter is an attribute to remove. It can be a space-separated list of attributes. |
