Chapter 15 ✦ The NN4 Layer Object (Chapter 31) } } Layer Clipping Properties Enter new clipping values to adjust the visible area of the layer. layer.clip.left: layer.clip.top: layer.clip.right: layer.clip.bottom: layer.clip.width: layer.clip.height: ARTICLE I Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances. 449 document.layerObject.clip
450 JavaScript Examples Bible: The Essential Companion to JavaScript Bible Listing 31-4 has a lot of other scripting in it to demonstrate a couple of other clip area techniques. After the document loads, the onLoad event handler initializes two global variables that represent the starting height and width of the layer as determined by the clip.height and clip.width properties. Because the tag does not specify any CLIP attributes, the layerObject.clip region is ensured of being the same as the layer’s dimensions at load time. I preserve the initial values for a somewhat advanced set of functions that act in response to the Reveal Original Layer button. The goal of this button is to temporarily shrink the clipping area to nothing and then expand the clip rectangle gradually from the very center of the layer. The effect is analogous to a zoom-out visual effect. The clip region shrinks to practically nothing by setting all four edges to the same point midway along the height and width of the layer. The script then uses setInterval() to control the animation in setClip(). To make the zoom even on both axes, I first make sure that the initial size of the layer is an even ratio: twice as wide as it is tall. Each time through the setClip() function, the clip.left and clip.right values are adjusted in their respective directions by two pixels and clip.top and clip.bottom are adjusted by one pixel. To make sure the animation stops when the layer is at its original size, I check whether the clip.top and clip.left values are their original zero values. If they are, I set a Boolean variable for each side. When both variables indicate that the clip rectangle is its original size, the script cancels the setInterval() action. Listing 31-15 in the JavaScript Bible demonstrates how to adjust clipping in IE5+ and NN6+ syntax. left top document.layerObject.left Compatibility ✓ NN2 NN3 NN4 NN6 IE3/J1 IE3/J2 IE4 IE5 IE5.5 Example To enable you to experiment with manually setting layerObject.top and layerObject.left properties, Listing 31-5 is a modified version of the layer.clip example (Listing 31-4). The current example again has the one modifiable layer, but it has only four text fields in which you can enter values. Two fields are for the layerObject.left and layerObject.top properties; the other two are for the layerObject.clip.left and layerObject.clip.top properties. I present both sets of values here to help reinforce the lack of connection between layer and clip location properties in the same layer object. You can find the corresponding syntax for IE5+ and NN6+ in Listing 31-16 of the JavaScript Bible.
