simply add the following attribute     for disabled i e  cannot highlight value or change disabled  disabled      for readonly i e  can highlight value but not change readonly  readonly    jQuery to make the change to the element  substitute disabled for readonly in the following for setting readonly attribute        fieldName   attr  disabled   disabled      or       fieldName   attr  disabled   true     NOTE  As of jQuery 1 6  it is recommended to use  prop   instead of  attr    The above code will work exactly the same except substitute  attr   for  prop

You can do this by simply marking it disabled or enabled   You can use this code to do this     for disable     fieldName   prop  disabled   true      for enable      fieldName   prop  disabled   false     or       fieldName   prop  readonly   true        fieldName   prop  readonly   false    --- Its better to use prop instead of attr

The setReadOnly state  is very useful for forms  we can set any field to setReadOnly state  directly or from various condition But I prefer to use readOnly for setting opacity to the selector otherwise the attr  disabled  also worked like the same way   readOnly examples      input   setReadOnly true     or through the various codition like  var same   this checked     input   setReadOnly same     here we are using the state boolean value to set and remove readonly attribute from the input depending on a checkbox click

In html       raisepay id   attr  readonly   true        raisepay id   prop  readonly  true     in bootstrap       raisepay id   attr  disabled   true        raisepay id   prop  disabled  true     JQuery is a changing library and sometimes they make regular improvements   attr   is used to get attributes from the HTML tags  and while it is perfectly functional  prop   was added later to be more semantic and it works better with value-less attributes like  checked  and  selected    It is advised that if you are using a later version of JQuery you should use  prop   whenever possible

There are two attributes  namely readonly and disabled  that can make a semi-read-only input  But there is a tiny difference between them    lt input type  text  readonly   gt   lt input type  text  disabled   gt     The readonly attribute makes your input text disabled  and users are not able to change it anymore  Not only will the disabled attribute make your input-text disabled unchangeable  but also cannot it be submitted    jQuery approach  1        inputID   prop  readonly   true       inputID   prop  disabled   true     jQuery approach  2        inputID   attr  readonly   readonly        inputID   attr  disabled    disabled      JavaScript approach   document getElementById  inputID   readOnly   true  document getElementById  inputID   disabled   true    PS prop introduced with jQuery 1 6
