This article is mainly on the JS set readonly value of the method is introduced, the need for friends can come to the reference, I hope to help you

In the Web page we sometimes need to control the text input box "input state", some key properties can not be modified, this time need to set the text input box ReadOnly property to False, in the Web page we can use <input name= "Txt_name" type= "Text" readonly= "readonly" id= "Txt_status" name= "Txt_name" style= "width:150px"/>; but in JS we can't eat txt_name.readonly   = "ReadOnly" To set this property, because JS is case-sensitive, so when invoking the property, we must use Txt_name.readonly=true to set it. Of course, the page text box also has a property to control its state, disabled, this property is to restrict the user to modify the contents of the text box, but this property is set to "disabled" after the C # background code can not get the content of the control.
