JavaScript - Search An Input Text For Key Words
Sorry, not sure if I need Javascript for this so I posted it in the html forum as well
I'm looking to create a simple page where a user can copy and paste a list of ingredients and then push a button to search that list for a number of key words. Key words: Amodimethicone, Trimethylsilylamodimethicone, Glycerin, Trideceth-12, Behenoxy, Bisamino, Aminoethyl, PG-Propyl, Phenylpropyl, Methicone, Cyclomethicone, Cyclopentasiloxane, Cyclohexasiloxane, Cyclopentasiloxane, Dimethiconol, Trimethylsiloxysilicate, Silicate, Siloxy, Trimethylolpropane, Diisostearoyl, Copolyol, Dodecylbenzenesulphonate, Diphenyl, silicone, Methicone, Simethicone, Trisiloxane, sulfate, Myreth, Lauryl, Laureth, Sulfonate, dodecylbenzenesulfonate, Xylenesulfonate, Ammonium, Isethionate, Sulfoacetate, Sarcosinate, Sulfosuccinate, Carboxylate, Taurate, glycinate I don't care how they are alerted if any of the key words match their ingredients pop up, highlight, whatever. *Incase anyone is wondering it is to search hair products for any form of silcones or sulfates since many people wish to avoid them but they come in many different forms. Thanks!! Similar TutorialsHi, I'm really new to Javascript. Recently in my IT class, we made a HTML page which would open a popup box, where the user could enter a key word. When the user pressed enter, the page would navigate to a specific page. The code we used was: Code: <script language = "JavaScript">
where = window.prompt ("Please tell me where you would like to go.");
switch (where){
case "Digg" :
window.location = "http://www.digg.com" ;
break;
default:
window.location = "http://www.google.com" ;
}

What I am hopeing to do, is implement this code on my workplaces server, and have the keywords link to other html documents within the server. However when I tested this, for some reason the links are not working. Can this actually be done? Am I missing something silly? Are there any other ways of doing this? Thanks in advance Hi all can someone guide me (total JS newbie) on this presumably pretty easy task? I have a "parent" page with some text inputs in it (a form). This is what I am after: -when the user clicks a link it pops open a new window via JS - "child" (this is working). -in the "child" window there are also some text inputs (another form) (done). -when the user changes the value for 'testChild_textInput_4' in the child window, then I want it to automatically set this same value, to effectively overwrite, what is currently in 'testParent_textInput_2' in the parent window. Presumably this involves an onChange event, but it is also OK with me if the needful (the text input's value in the parent window being overwritten) happens upon the child window's form submit. If anyone can show me either trick, I would be thrilled! I set up a test page to make this all easy to talk about: http://www.yellow-turtle.com/testDumpMe_parent.html Please let me know! Thanks! -John I am thinking this should be fairly easy but yet I am not getting far. I want to have a form with a single text imput field for a zip code. Depending on which zip code the user enters will determine which url they will be sent to. If they enter a zip code which is not in the script, they would be sent to a default url. I am also assuming this can be accomplished with javascript. Any help is greatly appreciated. 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> Hey, I'm working on an auto-suggest for our search function, but I am running into a wall (possibly due to lack of sleep). Basically, the user enters a search term, which searches our mySQL db, and if the search matches with a part number or description, it will output those results. My jam is that I would like the output to highlight the matching input, which I've gotten to work 95% correct. Code: for (var i=0;i<arr.length;i++) // Loop through results to indicate highlighting
{
// Test condition to see if input matches part number
if (this.sInp.toLowerCase()==arr[i].value.toLowerCase()) // Tests to see if input matches part number and highlights input to match
{
var val = arr[i].value;
var st = val.toLowerCase().indexOf( this.sInp.toLowerCase());
var output = val.substring(0,st) + "<em>" + val.substring(st, st+this.sInp.length) + "</em>" + val.substring(st+this.sInp.length);
var span = _b.DOM.cE("span", {}, output, true);
if (arr[i].value != "")
{
var br = _b.DOM.cE("br", {}); // Inserts line break
span.appendChild(br);
var small = _b.DOM.cE("small", {}, arr[i].info); // Produces second line (info or value)
span.appendChild(small);
}
var a = _b.DOM.cE("a", { href:"#" });
var tl = _b.DOM.cE("span", {className:"tl"}, " ");
var tr = _b.DOM.cE("span", {className:"tr"}, " ");
a.appendChild(tl);
a.appendChild(tr);
a.appendChild(span);
a.name = i+1;
// Modified to submit on click
a.onclick = function () { pointer.setHighlightedValue();
var formName = (pointer.oP.whereSubmit);
if (formName != null) {
var form = document.getElementById(formName);
form.submit();
}
return false; };
// End submit modification
a.onmouseover = function () { pointer.setHighlight(this.name); };
var li = _b.DOM.cE( "li", {}, a );
ul.appendChild( li );
}
else // Tests if input matches any part of description and highlights input to match
{
var val = arr[i].info;
var st = val.toLowerCase().indexOf( this.sInp.toLowerCase() );
var output = val.substring(0,st) + "<em>" + val.substring(st, st+this.sInp.length) + "</em>" + val.substring(st+this.sInp.length);
var span = _b.DOM.cE("span", {}, output, true);
if (arr[i].info != "")
{
var br = _b.DOM.cE("br", {});
span.appendChild(br);
var small = _b.DOM.cE("small", {}, arr[i].value);
span.appendChild(small);
}
var a = _b.DOM.cE("a", { href:"#" });
var tl = _b.DOM.cE("span", {className:"tl"}, " ");
var tr = _b.DOM.cE("span", {className:"tr"}, " ");
a.appendChild(tl);
a.appendChild(tr);
a.appendChild(span);
a.name = i+1;
// Modified to submit on click
a.onclick = function () { pointer.setHighlightedValue();
var formName = (pointer.oP.whereSubmit);
if (formName != null) {
var form = document.getElementById(formName);
form.submit();
}
return false; };
// End submit modification
a.onmouseover = function () { pointer.setHighlight(this.name); };
var li = _b.DOM.cE( "li", {}, a );
ul.appendChild( li );
}
}
// End Input Highlight
My issue seems to be my conditional statement. Basically, the user's input must match the part number ("value") exactly for it to output the results is a specific format. I would like it to be able to have something similar to mySQL's wildcard ("%") it will search the entire part number ("value") and not just the beginning to find a match. Sorry if this doesn't make much sense, I will attempt to clarify if needed, but again running on 0 sleep. Thanks for any help. Hello, I'm using google voice search on a simple form: Code: <form action="http://www.google.com/search">
<input type="search" name="q" speech required onspeechchange="startSearch">
</form>
How to activate the voice search, that is generally activated by clicking on the little microphone near the textbox, without clicking it? I want it to start recording the voice after the user starts talking, or alternatively, after a tot # of seconds.. I did not find anything on the API: http://www.w3.org/2005/Incubator/htm...api-draft.html I thank you in advance I'm having major pains trying to figure this out. I'm kind of new to Javascript, I need to open a text file from an external server, store each line in an array, then search that array for a certain word (HIGH), and if it exists then write something to the webpage, and if not, write something else. Here is what I have so far: Code: <html>
<head>
<title>Test</title>
<script>
<!--
function test(x) {
if (wxd1txt.readyState === 4 && wxd1txt.status === 200) { // Makes sure the document is ready to parse and Makes sure it's found the file.
var wxd1text = wxd1txt.responseText;
var wxd1array = wxd1txt.responseText.split("\n"); // Will separate each line into an array
var wxd1high = wxd1array.toString(); //Converting the String content to String
//var highsearchreg = new RegExp("HIGH");
//var wxd1high = wxd1array[x].search(highsearchreg);
document.write(wxd1high);
if (wxd1high.search("HIGH") >= 0){
document.write("HIGH RISK");}
else {
document.write("NO RISK");}
}

When added to a webpage, nothing shows up except the "Hi!" and there are no errors in the Javascript Console in Google Chrome. Is this possible with Javascript, and if so, what am I doing wrong or not doing? Also, I have 2 URLs, one is a text file that has the HIGH text I want for an example, the other is the current file, which shouldn't have HIGH in it (unless the weather in the US turns really bad) well title says it all i have a search form, and the default value is "enter text here" when the user click the submit button, i would like to check if the value of my text input is "enter text here" and if it is, then don't submit the form (popup a warning or something) how can i do that? thanks a lot! hi i wants to change one input to texarea when i select one from radio, plz any suggestion how i would do that? my code PHP Code: <input type="text" name="other" value="this need to become textarea" /> <input type="radio" name="inputtext" />Text <input type="radio" name="inputtext" />Textarea so when i click inputtext radio name"other" will become a textrea rather then input type text. thanks for any help. Hi, I have a form with text boxes which I need to display values ie. <input type="text" name="image_ref" value="image1" /> This works no porblem until I enter the below javscript onto the page: <script type="text/javascript"> var level1 = document.getElementById('level1'); level1.style.display = 'none'; var level2 = document.getElementById('level2'); level2.style.display = 'none'; var all_levels = document.getElementById('all_levels'); all_levels.style.display = 'none'; </script> This code is to hide certain parts of the form until they are activated. the problem is when the parts of the form are activated and displayed, the values inthe text input boxes do not show. Any ideas why this is? many thanks in advance. hi friends , i am on make a dynamic input field creation code , my problem is the entered text(value from "add proposition") is washing away , if i press new "add proposition" my java script is PHP Code: <script language="javascript" type="text/javascript"> function add() { k=document.getElementById("num").innerHTML k=parseInt(k); if(!k) {document.getElementById("num").innerHTML=1; k=1;} else{ document.getElementById("num").innerHTML=k+1; k++; } document.getElementById("cat").innerHTML+="<br />type propositon "+(k)+":<input type=\"text\" name=\"prop"+k+"\">is it answer? <input type=\"checkbox\" name=\"ans"+k+"\"> ignore this one:<input type=\"checkbox\" name=\"ign"+k+"\">" } </script> my html code is PHP Code: <form action="new.php" method="post"> <fieldset> <legend>Add Question & answer:</legend> question type:<br /> True or False:<input type="radio" name="radio" value="t"> Objective:<input type="radio" name="radio" value="o"> Other:<input type="radio" name="radio" value="o"> Quesion:<br /> <textarea name="desc" rows="6" cols="35" ></textarea> <br /> <a href="javascript:add()" ><b>add proposition</b></a> <div id="cat"></div> <div id="num" style="display:none;"></div> <br> <input type="submit" name="submit"> </fieldset> </form> how i solve this problem ? Currently I have several forms using the input text "field3". I want to know how I can require an HTML input text field to be required WITHOUT having to use the form name in the javascript and without modifying <body>,<form> or <input type="submit">. Also no HTML5 since not all browsers use it (life would be simple if they did since threres a required tag) So here is my form, for example Code: <form name = "test"> <input type="text" name="field1"> <input type="text" name="field2"> <input type="text" name="field3"> <input type="submit"> </form> In otherwords, I can only edit <input type="text" name="field3"> by putting code directly before, in, or after that input field. With this problem, how can I make it required? thank you hi folks, i needed a text input so the user that will register a product, will make sure to enter the cents, and not just the raw money, making it to be stored incorrectly on my database. for example, if i type "1" the output inside the text field will be automatically "0.01", so the user HAS to type the cents. thanks in advance I'm pretty much lost at javascript, and unfortunately can use php to accomplish this, so here goes........ I have existing html page that includes a Week #. ie, 1, 2, 3, 5.... and so on. I'd like to be able to have a text, csv, or similar file that I can update on frequent basis that will list a Week # and than custom field of some type. (likely a date or unix time stamp). Is there a way to open a text file (or csv, etc) in javascript. Than be able to compare and get the correct data? Off the top of my head, I think its possible, and would involve something like the following? 1. Create a csv file like below 1, this is custom, my other custom 2, some more, and this too 3, and somthing, see spot run 2. Next would be have a javascript open and read the file. You would assign a variable name to each 1st, 2nd and 3rd item of each line. Than the script would loop through each line until it found a a match of Variable 1 to the Week your looking for. You could then parse out and use the other variables from that line. Any of that make sense? I hope to try and experiment some later today or tonight if I can, but javascript is still pretty foreign to me. Hi, I'm currently programming a menu editing script and I'm trying to reorder value of text input on change. What I'm trying to do is when I change the value of a text box it reorders the others. EX Start 1 2 3 4 5 Change 3->1 End 2 3 1 4 5 Here is what I've manage to do, it works only when the number is bigger. Javascript function Code: function changeOrder(current)
{
var num_name = current.name.split("_",2);
var id = num_name[0]+"_"+num_name[1]+"_number";
var maxorder = document.getElementById(id).value;
var currentmax = current.name.substr((current.name.length-1),1)
if(currentmax <= maxorder && current.value > 0)
{
var start = (currentmax > current.value ? 1 : currentmax);
for(var i=start;i<maxorder;i++)
{
var k = parseInt(i)+1;
x = document.getElementsByName(num_name[0]+"_"+num_name[1]+"_order_"+k);
x[0].value = i;
x[0].name = x[0].name.substr(0,(x[0].name.length-1))+i;
}
current.name = current.name.substr(0,(current.name.length-1))+current.value;
}
}
HTML input Code: <input type="text" style="width: 20px;" onchange="changeOrder(this);" value="1" name="other_title_order_1"> Thanks for any advices you may have Maxetime I need a javascript that could record the ID/name of a textbox when the user hit delete or backspace to be used on the next page after submission in a PHP script. There are 96 text boxes, they are all randomly placed on the screen with a question that came from a randomized array's keys (the script later checks the values of the textboxes with the values from the array's keys that correlate to the textboxes by the name/id of the textbox, which is assigned by a for loop that issues the next($array) to assign everything everywhere. At the same time, it needs to count how many times the backspace/delete were pushed and have that recorded and sent as well. After 45 minutes of research I've been able to solve the "count the backspace/delete key" problem: Code: <script type="text/javascript">
var count = 0;
document.onkeypress=function(e){
var e=window.event || e
if (e.keyCode == 8) { //8 is backspace
count++;
document.getElementById('backspace').value=count; //this is a hidden input
}
if (e.keyCode == 46) { //46 is delete
count++
document.getElementById('backspace').value=count; //the hidden input
}
}
</script>
But onto the name/id issue: I'm not sure how to go about retrieving the names/id of the textboxes. I would assume a onkeypress event for every textbox, but hope that there could be something I could just add to this code. Thank you for your help. This is hopefully a simple fix and I hope someone can help me out, I'm pretty new at coding. I have a form on an html page and I want to make it so when a button is clicked, it adds one to the input to the right of it, and when a button to the right of the input is clicked, it will delete one to the left of that button. I don't want to resort to making a new function for each and every form, because there will be a lot. Here is the form and input parts: Code: <form name="calculate"> <input type="button" onClick="add()" /> <input name="result" type="input" readonly="readonly" value="0" /> <input type="button" onclick="sub()" /> </form> Here is what the function code looks like: Code: function add()
{
var add = 1 * calculate.name.value;
add = add + 1;
calculate.name.value = add;
}
function sub()
{
var add = 1 * calculate.name.value;
add = add - 1;
calculate.name.value = add;
}
Note: where I called the calculate.name.value, that obviously doesn't work, and I need some way, rather than making multiple functions and changing the name part, to be able to call to a name near the button, if at all possible. Any and all ideas are appreciated, Thanks! I'm trying to reduce the height of input buttons, but am unable to center the text vertically. Tried every css trick I know, but the text is still too low (I can make it lower :P). Any way to do this?
I'm building a template editor and need some help changing some of the variables. Part 1. Only at DEALERNAME. Must present coupon at time of write-up.
