AJAX Suggest and AutocompleteFigure 6.3: PHP Knows Many Functions That Start with "s"12. OK, PHP has many functions that start with letter s. Observe that the first matchingfunction is autocompleted in the search box and that you have a long list of functionsto scroll through. Let's type the second letter of the word strstr: t.13. The list of functions has diminished as expected. Find the function you are interestedin by continuing to type its name, or by using the keyboard's up and down arrows, orusing the mouse. When you have found it, press Enter or click it using the mouse.182
Chapter 6Figure 6.4: PHP Documentation for strstrWhat Just Happened?Let us start with the index.html file.The interesting part in this script is that a scroll region can be implemented in DHTML. A littlepiece of heaven regarding scrolling can be found at http://www.dyn-web.com/dhtml/scroll/.The idea for having a part of the page with a scrollbar next to it is to have two layers one insideanother. In our example the div scroll and the div suggest do the trick.The outer layer is scroll. It has a fixed width and height and its most useful property isoverflow. Generally, the content of a block box is confined to just the content edges of the box.In certain cases, a box may overflow, meaning that part of its content lies outside the box. In CSS,the overflow property specifies what happens when an element overflows its area. You can findthe possible values of overflow at http://www.w3.org/TR/REC-CSS2/visufx.html.Another thing that can be interesting is how we can center an object horizontally. The classic align= center attribute is not valid in XHTML 1.0 and therefore a workaround needs to be found. Thesolution is to use the margin attribute set to auto for the element you want centered. If you have avalid doctype, Internet Explorer 6 will render an element having auto margins centered; otherwise,as is the case with the earlier versions, the attribute will be ignored. For earlier versions of InternetExplorer, you need to have the text-align attribute set to center for the parent of the element you183
