Note:To retrieve and change DOM properties such as the checked, selected, or disabled state of form elements, use the  method

e.g:

//suppose ele is a checkboxif(ele.checked)if(ele.prop('checked'))if(ele.is(':checked'))

asGet:Get the computed style properties for the first element in the set of matched elements.

asSet:Set one or more CSS properties for the set of matched elements.

: Add or remove one or more classes from each element in the set of matched elements, depending on either the class's presence or the value of the state argument.

asGet:Get the current value of the first element in the set of matched elements.

asSet:Set the value of each element in the set of matched elements.

.

asGet:Get the combined text contents of each element in the set of matched elements, including their descendants.

asGet:Get the current coordinates of the first element in the set of matched elements, relative to the document.

asSet:Set the current coordinates of every element in the set of matched elements, relative to the document.

Note:The .offset() method allows us to retrieve the current position of an element (specifically its border box, which excludes margins) relative to the document.Contrast this with , which retrieves the current position relative to the offset parent.

position()返回相对于父元素的偏移量

width()height()获得元素的宽高，不包括内外边距及边框，设置时会受到盒模型的影响

innerWidth()innerHeight()包含内边距

outerWidth()outerHieght()包含内边距及边框

asGet: Set Return the value at the named data store for the first element in the jQuery collection, as set by data(name, value) or by an HTML5 data-* attribute.

asSet: Store arbitrary(任意的) data associated with the matched elements.

Note:Using the object directly to get or set values is faster than making individual calls to .data() to get or set each value:

var mydata = $( "#mydiv" ).data();if ( mydata.count < 9 ) {  mydata.count = 43;  mydata.status = "embiggened";}
