I have an anchor in my HTML. it has a page attribute with a value. So everytime it is clicked I use the page attribute value in my js. Now I want to set a style attribute with a background color to show that a certain a element is selected. So I have to select the element by page attribute and add a new attribute with a value to the a element.
How do I handle that?
With HTML like:
<a href='#' page='1'>Link 1</a><br />
you could do:
$('a[page=1]').addClass('selected').attr('test', 'hi!');
(ie better to change display using a css class [eg 'selected'] than the style attribute - but the attr call there shows how to add an attribute).
To select an element by attribute value, you can use this syntax:
$('[attribName="value here"]')
Where attribName
should be replaced with attribute name such as name
, title
, etc.
To add a new attribute value, you can use the attr
method.
Example:
$('[attribName="value here"]').attr('attribute name', 'attribute value');
And this is how you can change the background color:
$('[attribName="value here"]').css('background-color', 'green');
Note you should replace dummy attribute names and values as per your requirements.
不确定你在问什么..你需要找到具有“页面”特定值的元素并更改其背景吗?
$("a[page='value']").css('background-color', 'color-code');
