Hi, How can I strip out the dirty characters shown in textarea after to extract the tags from a webpage and before submitting to another page? By dirty characters I take in mind the characters shown in the image below. - Replacing double space with a unique space - Replacing "squares" with a blank space - delete contents between "<!--" and "-->" or "<?" and "?>" Jan Lee Hello I have this snippet for controlling the number of characters entered in a textarea. It works. But, if I replace in this code the name "my_form" by "contact-form" and "my_text" by "message", it doesnt ! It looks like the keyword is " my_form ". You change that , and the script will not work! It turns out that I have to change those names because the form as it was already had those names my_form and message before I added this counter And I dont want to replace the names of the form in order to adapt them to this code snippet below. The question is why would the script not work if I have just replaced two words, which dont seem to be keywords of JS programming (my_form and my_text) <html><head> <title>(Type a title for your page here)</title> <script language=JavaScript> <!-- function check_length(my_form) { maxLen = 50; // max number of characters allowed if (my_form.my_text.value.length >= maxLen) { // Alert message if maximum limit is reached. // If required Alert can be removed. var msg = "You have reached your maximum limit of characters allowed"; alert(msg); // Reached the Maximum length so trim the textarea my_form.my_text.value = my_form.my_text.value.substring(0, maxLen); } else{ // Maximum length not reached so update the value of my_text counter my_form.text_num.value = maxLen - my_form.my_text.value.length;} } //--> </script> </head> <body> <form name=my_form method=post> <textarea onKeyPress=check_length(this.form); onKeyDown=check_length(this.form); name=my_text rows=4 cols=30></textarea> <br> <input size=1 value=50 name=text_num> Characters Left </form> </body> </html> I have been using code such as Code: a=a.replace(/ /g,''); b=b.replace(/;,/g,';'); to eliminate spaces in a string, as well as converting things like ";," to ";" in strings. Several instances of these replacements will have to occur in the strings. Unfortunately, I cannot make it work for converting two commas into one or for eliminating line breaks. Does anyone know how to do this (preferably without using "while")? I'm finishing up an e-commerce website, and I can't quite figure out why the shopping cart feature is acting all screwy in Internet Explorer. It works fine in Firefox, but in IE, when you add a product to the cart it doesn't display the little pop-up notification, and when you click on the "my cart" at the top right the product quantities are incorrect about 70% of the time. For some reason IE keeps doubling the quantities; I think one of the scripts may be double refreshing the page I just can't figure out where. If anyone has any suggestions they would be much appreciated. The site I'm referring to is he www.tcatvs.com Thanks y'all! Also I'm using the jquery framework for much of the site. I am working on my personal portfolio site, and am using a code that will make each portfolio piece appear in a new div when the name of the piece is clicked on. The problem is, JS does not seem to recognize double digits. I am not familiar with JS at all, I just got comfortable with CSS/HTML a few weeks ago! I am in over my head. It would really, really help if someone could show me how to change the code so that I could make about 15 to 20 divs instead of 9. Here is the code: Code: <script language="JavaScript"> numdivs=9 IE5=NN4=NN6=false if(document.all)IE5=true else if(document.layers)NN4=true else if(document.getElementById)NN6=true function init() { showDiv(0) } function showDiv( which ) { for(i=0;i<numdivs;i++) { if(NN4) eval("document.div"+i+".visibility='hidden'") if(IE5) eval("document.all.div"+i+".style.visibility='hidden'") if(NN6) eval("document.getElementById('div"+i+"').style.visibility='hidden'") } if(NN4) eval("document.div"+which+".visibility='visible'") if(IE5) eval("document.all.div"+which+".style.visibility='visible'") if(NN6) eval("document.getElementById('div"+which+"').style.visibility='visible'") } </script> Thank you for taking the time to read this! Hopefully someone can help. Hi, I'm Sam and I'm new to this forum. I have a few question about double combo box. Before I get down on details I have to confess that my knowledge about javascript is almost zer0 so if you're posting any answer please elaborate. I've found this code somewhere online and I'd like to make some changes to this code. I've searched everywhere but couldn't find any answer yet. As you can see in this code, the javascript function can open a page in iframe once the user clicks on "Go". I'd like to know how to add links to the options in the first box so that it can open an iframe by itself, plus loads the next box , so when the user selects an option from the first box, the first box opens a page in iframe then loads the options for the second box. There should be two iframes side by side, the first iframe to open a page for the first box once the user selects the options in the box and the second ifram opens a page for second box once the user clicks on the "go". I just don't know how to add links to the options in the first box. Here's the code: Code: <html> <head> </head> <body> <form name="doublecombo"> <p><select name="example" size="1" onChange="redirect(this.options.selectedIndex)"> <option>Technology Sites</option> <option>News Sites</option> <option>Search Engines</option> </select> <select name="stage2" size="1"> <option value="http://cssdrive.com">CSS Drive</option> <option value="http://www.news.com">News.com</option> <option value="http://www.wired.com">Wired News</option> </select> <input type="button" name="test" value="Go!" onClick="go()"> </p> <script> <!-- /* Double Combo Script Credit By JavaScript Kit (www.javascriptkit.com) Over 200+ free JavaScripts here! */ var groups=document.doublecombo.example.options.length var group=new Array(groups) for (i=0; i<groups; i++) group[i]=new Array() group[0][0]=new Option("CSS Drive","http://cssdrive.com") group[0][1]=new Option("News.com","http://www.news.com") group[0][2]=new Option("Wired News","http://www.wired.com") group[1][0]=new Option("CNN","http://www.cnn.com") group[1][1]=new Option("ABC News","http://www.abcnews.com") group[2][0]=new Option("Hotbot","http://www.hotbot.com") group[2][1]=new Option("Infoseek","http://www.infoseek.com") group[2][2]=new Option("Excite","http://www.excite.com") group[2][3]=new Option("Lycos","http://www.lycos.com") var temp=document.doublecombo.stage2 function redirect(x){ for (m=temp.options.length-1;m>0;m--) temp.options[m]=null for (i=0;i<group[x].length;i++){ temp.options[i]=new Option(group[x][i].text,group[x][i].value) } temp.options[0].selected=true } function go(){ document.getElementById("search").src=temp.options[temp.selectedIndex].value } //--> </script> </form> <iframe id="search" name="photos_frame" src="my_photo_page_needs_to_load_into_this_frame.htm" width=800 height=400 marginwidth=0 border=1 marginheight=0 hspace=0 vspace=0 frameborder=0 scrolling=no></iframe> </body> </html> Hello, I'm trying to achieve what seems pretty simple, I have achieved both aspects successfully by themselves but together I have not I am trying to submit a form data via post, then I'm also trying to redirect I have got the window.location working I have the database writing working however I can't seem to get them to work sequentially I think the reason is that the post action redirects to itself, then the initial setinterval request is gone I try to do the sequential action this way Code: <a href=# onclick="document.forms['frm'].submit();redirect();">Submit</a> So, either the data posts and I'm stuck at the same page, or it redirects and the data doesn't post What am I missing? I read that to have multiple functions by one click, you separate them with a semi-colon as I have done I think as I mentioned that the key is the post to PHP_SELF which "nullifies" the redirect request eg. it never existed So what do I do? Also I'm not after the time interval, I was just trying to find a way for a user to be notified "Hey you're going to be redirected" by an alert (which I had this pop up working as well) then when they press okay, they are redirected. Ideally the user enters data, data is stored, pop-up, hit okay, redirect Thanks for any help document.write(str.replace(/(\+|\(|\)|.|-|\/ /g,'')); feeble attempt to remove '.' '(' ')' ' ' '-' '/'and '+' hi all, am doing a check on my fields, so that they only contain certain characters and numbers. i have this. var validEntry = /^[a-zA-Z0-9@$&"]+/; but this also captures a space in between words as an error. can somebody please tell me on how to avoid this. thanks. So, I have this javasript code in HEAD <script type="text/javascript"> <!-- function validateThis(registerForm) { if (registerForm.firstname.value == 'Name') { alert("Oops"); return false; } else { return true; } } //--> </script> with this form in BODY <form action="register.php" method="post" name="registerForm" onSubmit="return validateThis(this)"> <input type="text" value="Name" onclick="if(this.value=='Name'){this.value=''}" onblur="if(this.value==''){this.value='Name'}" name="firstname"> </form> and I want to put a text with Greek characters instead of value "Name". I tried it and the "function validateThis" didn't work. The form just passes it and returns true. I tried also hexadecimal code,HTML entities and numeric HTML entities and didn't work either. What I should I do? Thank you in advance! I'm currently working at school on a website and I cycled through aloooot of tutorials, but I couldn't find anything >.< so the qeustion is how to make a VERY simple javascript div tag replacer using buttons. so if I click for example button 1 then I want div tag 1 replaced with div tag 2 and when you press button 2 div tag 1 or 2 gets replaced with div tag 3. the closest tutorial I found was: Replace one div with another Code: s = s.replace(/\[code\](.*?)\[\/code\]/gi,'<span class="code">$1</span>'); This works as expected, but what I'm trying to do is replace the content within the tags with a santized version of what was in it before. Example Code: function clean(str){ //clean up string stuff here return str; } s = s.replace(/\[code\](.*?)\[\/code\]/gi,'<span class="code">'+clean('$1')+'</span>'); But as with everything in life it's never that easy, it's simply passing "$1" to the clean function instead of what was actually within the code tags. Can anyone tell me how I'd go about doing this? Hi I am wondering if it is possible to replace a rating form with some sort of javascript star rating system that would submit the same way? Here is my current form: <form method=post action="%%%SCRIPT_URL%%%"> <input type=hidden name=main value="imageRate"> <input type=hidden name=file value="%%%FILENAME%%%"> <input type=hidden name=category value="%%%DIRECTORY%%%"> <select name=rate size=1> <option>1</option> <option>2</option> <option>3</option> <option>4</option> <option>5</option> <option>6</option> <option>7</option> <option>8</option> <option>9</option> <option>10</option> </select> <input type=submit value="Rate This!"> </form> Right now it is a drop down menu and I would like to replace with a php, javascript, or ajax rating script that can keep the same properties. Any advice? Is there an inbuilt function in javascript to convert web characters like
Code: & back to '&' for use in a search text field? Hi everyone. I do all of my writing and editing in notepad but can't figure out how to use characters from different charsets in the same script-block. For example if I wanted to write Code: if ( CharInput=="ش" ) { N = 1;} if ( CharInput=="厜" ) { N = 2;} I've found the unicode the number for ش is 0634 and 厜 is 539C. But I don't know how to use them. My question is how do I modify the above piece of code so it works in something like notepad? I can't cut and paste them in because in plain text files like that of notepad the formating is lost and I'm pretty sure html wouldn't allow that anyway. Thanks for reading Hi, I need a javascript that detects flash and replace z-index value. i have 2 div. div1 (alternate HTML content) has z-index=-3 and div2 (flash object) z-index=0. If flash is detected, do nothing. if flash is not detected, i would like to set div1 z-index to a positive 3. can someone please help me? I have a js replace function to replace text next to two radio buttons on a pre set form. Script is as follows. Code: document.body.innerHTML = document.body.innerHTML.replace( "Payment by <b>Moneybookers</b> e-wallet<br>", "" ); document.body.innerHTML = document.body.innerHTML.replace( "Maestro, Visa and other credit/debit cards by <b>Moneybookers</b>", "Pago con Diners Club, Mastercard o Visa" ); The script works fine in Chrome and Firefox, however, the script is not actioned in Explorer. I believe it has something to do with there being , / - within the text I am replacing? When I use the function to replace text with no , / - in the text - it works fine in explorer, however, for example when I try to replace text.. - "Maestro, Visa and other credit/debit cards by Moneybookers" this does not work in explorer.. I'm assuming because of the coma and forward slash. Honestly I've tried everything but just can not get this to work. I have no access to the HTML table where the form is posted this is why I am attempting this funtion. Any help would be greatly appreciated!! I was debugging my code looking for a loop. So in the process I added a confirm request and if the user clicked cancel I coded location.replace("Kill.html"). Problem was that the JAVASCRIPT continued to run until either it finished or I used the Task Manager to end the session. There3 was a small difference in browsers: Firefox put up the new screen while continuing to run the JAVASCRIPT while IE didn't put up the new screen until after the JAVASCRIPT was finished. I could tell the JAVASCRIPT was still running because the confirm messages kept popping up.
