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.
