Filling In Forms
Back in the Dark Ages of the Web (that is, in 1993), Web pages were just pages to look at. Because that wasn’t anywhere near enough fun or complicated enough, Web forms were invented. A form is sort of like a paper form, with fields you can fill out and then send in. Figure 18-6 shows a typical form.
Figure 18-6: Just fill out a few forms.White boxes in a form are fill-in text boxes in which you type, in this case, your name and e-mail address. Little square boxes are check boxes, in which you check whichever ones apply (all of them, we hope, in this case). Little round buttons are radio buttons, which are similar to check boxes except that you can choose only one of them from each set. In Figure 18-6, you also see a list box, in which you can choose one of the possibilities in the box. In most cases, you see more entries than can fit in the box, so you scroll them up and down. Although you can usually choose only one entry, some list boxes let you choose more.Forms also include buttons. Most forms have two: one that clears the form fields to their initial state and sends nothing, and one, usually known as the Submit button, that sends the filled-out form back to the Web server for processing.After the data is sent from the form back to the Web server, it’s entirely up to the server how to interpret it.Some Web pages have search items, which are one-line forms that let you type some text for which to search. Depending on the browser, a Submit button may display to the right of the text area, or you may just press Enter to send the search words to the server. For example, the Google search page at google.com has a box into which you type a word or phrase; when you press Enter or click the Google Search button, the search begins.
One of the worst innovations in recent decades is pop-up windows that appear on your screen unbidden (by you), when you visit some Web sites. Some pop-ups appear immediately, some are pop-unders that are hidden under your main window until you close the main window. The pop-ups you’re most likely to see are ads for spy cameras, airline tickets, and mortgage refinancing (no, we’re not going to give their names here; they have plenty of publicity already).Mozilla and Netscape shocked us all by giving users something they actually want, a way to get rid of pop-ups. On the menu for either, open the Preferences window via EditPreferences, double-click Privacy & Security to expand it if it’s not already, and then Popup Windows. Click the Block Unrequested Popup Windows box, and your pop-ups, for the most part, disappear. In older versions of Mozilla that don’t have a Popup Windows panel, click Advanced to expand its list, and then Scripts & Plugins, and in that window uncheck the Open Unrequested Windows check box.In Konqueror, open the KDE Control module via SettingsConfigure Konqueror, click Java & Javascript at the left, and then in the window that appears click the Javascript tab at the top and (at last!) two-thirds of the way down you find JavaScript Web Popups Policy. The four options are Allow (not recommended), Ask (pop up a window asking if you want a popup, not much of an improvement), Deny, or Smart. Try Smart, to let it guess which pop-ups are useful, or Deny to get rid of all of them.
