    replacing text in .html page

    I have a page with a table (three columns). The left column holds the site's main menu. The right column holds pointers to articles. The centre column holds several text blocks. I want to replace one of those text blocks with another according to which pointer the user clicked in the right...

    if ((y=="") && (isNaN(parseInt(y))))

    Maybe everybody knows this, but I learned it the hard way: Javascript treats y=="" and y==0 as being the same. I have a little program that solves nonlinear equations online, see: http://www.engs-comp.com/solvnonlinearequ/index.html The evaluation function returns "" if an...

    Where is the bottleneck?

    How many bottlenecks are there to the loading of a web page? I can identify three, but there are probably more: 1. The design of the page can cause it to load slow. 2. The server that supplies the page can be overloaded. 3. The ISP that calls the page can be choked up. Is there any way of...

    Can't use <Back> button from a redirected page

    If I redirect from the index.html of my site to another page, say main.html, the <Back> button takes me back to index.html, which redirects me back to main.html. To get out from this infinite loop, I have to use the <Back> button's history. Anyone know of a better way? It's a problem I have...

    Quietly notify by email onLoad of a page

    Below are some code snippets, the purpose of which is to quietly notify me by email when a particular site is requested. You can see that I use Matt Wright's famous formmail.cgi, which insists on sending the user to a redirect page. This email code is in the index.html of the site. The site's...

    Can a web page send an email on being loaded?

    Don't ask why I should want this. If your page gets hundreds or thousands of hits per day, you wouldn't want it. But my pages get one hit every few days. I would like the page to send me an enmail when it gets hit. 1. Can this be done? 2. If so, how, and what information can it send? Thank...

    to count or not to count?

    Having had such a great response to my question &quot;to frame or not to frame?&quot;, I am hopeful to get an answer to the current question. Putting a counter on a page seems to create a huge overhead. See http://www.engs-comp.com/ and you will note that the page takes a fraction of a second...

    To frame or not to frame?

    I often see the advice NOT to use frames. Is this advice outdated or are there still valid reasons for it? Personally, I like frames because my menu of links (in the left margin) is stationary while the main page is being scrolled. I use a dark background for the menu area and a white...

    Can I fix a map on the monitor?

    Hi, all, thank you for such a lively forum. I have a background that moves with the vertical scrollbar and is implemented in the <BODY> tag thus: <BODY style=&quot;background-repeat: repeat-y; background-image: url('..\curvie.gif')&quot;> I have a map which serves navigation and would like...

    How do you know who I am?

    It doesn't matter how I come to this site - from email, or by search engine, or by typing its address - you know who I am as soon as I get there. Please tell me how you do this because I want to be able to identify visitors to my site in the same manner. It's probably some simple trick and...

    Can I preload a HTML page?

    My site has a pre-set tour of web pages. I would like to preload the next *.HTML while the user is viewing the current page, hoping that it would then load faster. Can this be done? If so, how? Thank you all, Helmut

    Anyone still using CA-Realizer?

    I have written a major application in CA-Realizer, which I am currently porting to 32-bit. Computer Associates no longer support the language. There are some bugs. For most, I found a work-around, but a few defy me. Is anyone else still using this language? Please talk to me.
