Jquery sets readonly and disabled of elements.

Jquery sets readonly and disabled of elements.

The Jquery api provides a method to apply the disabled and readonly attributes to elements, which is recorded here. As follows:

1. readonly

$ ('Input '). attr ("readonly", "readonly") // set the input element to readonly $ ('input '). removeAttr ("readonly"); // remove the readonly attribute of the input element if ($ ('input '). attr ("readonly") = true) // determines whether the readonly attribute has been set for the input element.

There are two ways to set the readonly attribute for the element and cancel the readonly attribute:

$ ('Input '). attr ("readonly", true) // set the input element to readonly $ ('input '). attr ("readonly", false) // remove the readonly attribute of the input element $ ('input '). attr ("readonly", "readonly") // set the input element to readonly $ ('input '). attr ("readonly", "") // remove the readonly attribute of the input element

2. disabled

$ ('Input '). attr ("disabled", "disabled") // set the input element to disabled $ ('input '). removeAttr ("disabled"); // remove the disabled attribute of the input element if ($ ('input '). attr ("disabled") = true) // determines whether the disabled attribute has been set for the input element.

There are two ways to set the disabled attribute and cancel the disabled attribute for the element:

$ ('Input '). attr ("disabled", true) // set the input element to disabled $ ('input '). attr ("disabled", false) // remove the disabled attribute of the input element $ ('input '). attr ("disabled", "disabled") // set the input element to disabled $ ('input '). attr ("disabled", "") // remove the disabled attribute of the input element
