The TextField written in the program is as follows:
In order to call this name in JavaScript, it gives it an individual name (StyleId = "Shry").
Now you have to click on a button, change this component's readOrthly value into false in the JavaScript function. First try to use Document.Forms [0] .shry.readonly = false This statement directly assigns readOnly to false, so that it can be implemented, and the results are not reacted. Later, I use Alert (Document.Forms [0] .shry.readonly) to print this property, display Undefined, indicating that JavaScript can't find this attribute. Later, I found a method getElementById (), so use Document.GtelementByid ("shry"). Readonly = false; to assign it to it, the problem is solved! !
