Examples of the differences between attr and prop of jquery

• For HTML elements that have intrinsic properties, use the Prop method when processing.
• For HTML elements our own custom DOM properties, when processing, use the Attr method.

HTML file

<tr>                        <th></th>                        <td>                            class= "Easyui-linkbutton" style= "width:60px;" Onclick= "SelectAll ()" > select all </a>                            class= "Easyui-linkbutton" style= "width:60px;" onclick= " Unselectall () "> select all </a>                        </td>                    </tr>

JS file

Assign a property value to a checkbox of the same name

function SelectAll () {    $ (' input[name= "Groupitem"] '). Val (function (index,val) {                $(This ). Prop (' checked ',true);
$ (this). attr (' checked ', true);//        error return  val;    })} function Unselectall () {    $ (' input[name= ' Groupitem "] '). Val (function (index,val) {                $ (  this). Prop (' checked ',false);
                //$ (this). attr (' checked ', false); error         return val;    })}
