jQuery – get element by id, class, name

admin programming Comments Off on jQuery – get element by id, class, name

In jQuery, you can get elements with CSS class name and id easily.

For example,

1. ID: #id

  • $(‘#idA’) – selects all elements that have an id of ‘idA’, regardless of its tag name.
  • $(‘div#idA’) – selects all div elements that has an id of ‘idA’.

2. Class: .classname

  • $(‘.classA’) – selects all elements that have an class name of ‘classA’, regardless of its tag name.
  • $(‘div.classA’) – selects all div elements that has an class name of ‘classA’.

3. Class: [name=”value”]

  • $(‘div[name^=”nameA”]’) – selects all elements that have an name of ‘nameA’, regardless of its tag name.
  • e.g. [name*=”value”], [name~=”value”], [name$=”value”]

3. Change attr: $(‘#idA’).attr()

  • $(‘#idA’).attr(‘src’, ‘value) – change value of attribute that have an idof ‘idA’, regardless of its tag name.
