如何以编程方式更改破折号中按钮的可见性？

Question

i'm using dashcode for a webapp and in order to add a + button in the browser bar to a specific view i need to hide and unhide that + button. The problem is i really don't know how to do this. I tried to write on the screen all the button's properties and in fact there is a visible parameter but when i display the value it shows "null" knowing that the button is visible...

So anyone has got an idea ? Thanks a lot !

Answer 1

you can do this in two ways.

1)use display and toggle it (block/none) 2)use visibility and toggle it (visible/hidden)

If you want to know the difference between display and visibility, look at display docs

Answer 2

put the button in a div

<div id="peekaboo">button</div>

then in the css set the visibility of peekaboo to the initial state visible or hidden then write a JavaScript function which will switch the css style state to visible or hidden as required.

Sorry i am away from my base computer so cannot access the code samples. can post better code tonight if you still need it
