JavaScript - How To Create Color Pallet Using Javascript?
Hi
i have an requirement i.e., i need to allow user to select one of color from color pallet and i need to store that color code value in database, how can i do this I am using jsp and js and html . Similar TutorialsHi, I'm faced with a problem trying to set background color under IE7. I have the following Javascript: Code: function showLayer793BKColor(id)
{
var txtObj = document.all(id);
if (txtObj.style.display == 'none')
{
txtObj.style.display = ''
txtObj.style.backgroundColor = 'grey';
}
}
function hideLayer793BKColor(id)
{
var txtObj = document.all(id);
if ( txtObj.style.backgroundColor == 'grey' )
txtObj.style.display = 'none';
}
These functions are used to show or hide div blocks. These blocks are, for example, specified in the following way: Code: <div id="l_gct5tekst" style="display:none"> <b>GCT 5. Eerste verkenning problematiek</b> and, for example, Code: <div id="l_Keuze" style="display:none"> <br/> <b>GCT 5</b> <br/> </div> The whole configuration works smoothly when using IE8. However, when using IE7 I get an error msg like "Invalid value for property". When I use the Color propert iso the BackgroundColor property I get no error anymore but of course I don't have a background color anymore then. In what way can I specify the use of a background color under IE7 ? Or is just not possible in one way or the other. Furthermore, what more differences between JS under IE7 and IE8 do I have to take into account ? Do I also have to rewrite my div block in some way (using some attribs ?) to cope with IE7 ? Thanks in advance, Diederick van Elst i have a javascript running on my web page, however the text in the input field is white, on a white background. making it unreadable. is there a way to change the text color for the script. site can be viewed he www.barren-county.net the script running is the toolbar at the bottom, more specifically the "Connect" app on the right, if you open it you see that the text field is white and text is invisible. here is the code i have: Code: <head>

can you help? Hi, Looking for some help with something, I have a table with 20 columns, Im looking to color code column 7,8,9,10,11,12. all of the data is numeric. Here is how they should be colored. column 7 (column header name is test7) if >50 should be red if 41-50 should be yellow if <=40 should be green column 8 (column header name is test8) > 40 should be red 32-40 should be yellow <=31 should be green this is similiar for other colums, if someone could help with this one I could figure out rest. thanks jay when creating a button with javascript, is it possible to change the blue color when you mouse over it? I know its a stupid question but I am curious... I'm new to this javascript stuff..
I'm not 100% sure if this can be done (I haven't been particularly successful in my Google searches). I'm using Javascript and forms to create conditional information randomizers for data. An example might be "What should you have to eat?" The person can generate a random result or select restrictions (selecting an allergy to X would eliminate X-related results). I prefer to work with black backgrounds. Even if I end up changing a default site layout to non-black (for audience purposes), I'd want a personalized CSS for myself. I'm running into some difficulty determining how to make my textarea black. Is there a way to apply CSS to textarea boxes (including those related to javascript?) Ideally, I'd like to be able to automatically style every textarea but if that is not possible in relation to javascript, I'd settle for changing the code for individual boxes. I was unsure where to place this topic so feel free to move it if it's better suited for CSS. Thanks *** I figured I didn't need to bump my post needlessly, but Thanks to "devnull69" as the provided solution worked. For some reason, I was confused about how to type that operation in css properly. That's probably one of the problems that arises when one combines staying up late with learning multiple programming languages at the same time. All is well now. here is my problem i need to set the color of a text here is what i need to change Code: <div style="position:absolute; left:10px; top:100px; width:250px; text-align:center;"> <font color="lightgreen" size="6"><b>* Mileage *</b></font><b> <font color="black" size="6"><div id="bullet4">Not Specified</div></font><br></b> <font color="lightgreen" size="6"><b>* Gearbox *</b></font><b> <font color="black" size="6"><div id="bullet5">Not Specified</div></font><br></b> <font color="lightgreen" size="6"><b>* Engine size *</b></font><b> <font color="black" size="6"><div id="bullet6">Not Specified</div></font><br></b> <font color="lightgreen" size="6"><b>* Body style *</b></font><b> <font color="black" size="6"><div id="bullet7">Not Specified</div></font><br></b> </div> now i need to set the color from a text file server side so far i can set the contents of the div serverside but the customer needs to be able to change the color of the innerhtml . now i would like to store the color in a text file color.txt i can make the code to change the txt file myself inside the color.txt would be "lightgreen" or other color how would i go about this. so in basic terms i need to set the color of the text from a color.txt file sat next to the index.html Hey guys, I have been trying to get better at my javascript as of late and there is this one particular color fading technique I have found that I am having trouble dissecting. The following code appears to be how they are making a rollover go from a dark gray to a subtle light gray with a nice fade but I can't exactly tell whats going on from the code. Is it just telling it to add a rgb point in so many seconds? Any professional help would be greatly appreciated. Code: colorInit=
true}b.elem.style[a]="rgb("+Math.max(Math.min(parseInt(b.pos*(b.end[0]-b.start[0])+b.start[0],0),255),0)+","+Math.max(Math.min(parseInt(b.pos*(b.end[1]-b.start[1])+b.start[1],10),255),0)+","+Math.max(Math.min(parseInt(b.pos*(b.end[2]-b.start[2])+b.start[2],0),255),0)+")"}});

Thanks. Hi guys, Am creating a web page in which a user searches a customer using customer id. The results are then displayed in a table. This is working fine. In addition to this, I have created another form in which a user enters a value in a textbox. This value is then compared to the results obtained in the previous table.The values below should be shown in green and those above in red (identical values may be shown in amber). This should be acomplished using javascript. My code is as shown below: PHP Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Search Script</title> <script type="text/javascript"> function hallo(){ var value1=200 var inputVal = window.document.getElementById("one").value; //alert(negNum); if(inputVal > value1){ window.document.getElementById("color").style.color="red"; } else if(inputVal < value1) { window.document.getElementById("color").style.color="green"; } else if(inputVal == value1) { window.document.getElementById("color").style.color="#FF7E00"; } } </script> </head> <body> <form> Value1: <input type="text" name="one" id="one" ><br/> Value2: <input type="text" name="two" id="two" value="" onClick="hallo();"> <br/> Value3: <input type="text" name="three" id="$cell" value="test data"> </form> <?Php require_once("database.php"); $CustID=$_POST['CustomerID']; $query="SELECT c.*,r.Meter_No,r.January,r.February,r.March,r.April,r.May,r.June FROM customer AS c,readings AS r WHERE c.CustomerID=r.CustomerID AND c.CustomerID='".$CustID."'"; $result=mysql_query($query) ; //If no matching records are found in the database,the code below will display a customized error message $num=mysql_numrows($result)or die("No Matching Records Found In The Database!"); $fields_num = mysql_num_fields($result); echo "<h3>Historical Meter Readings</h3>"; echo "<table border='0'cellspacing='5' cellpadding='5' id ='three'><tr>"; // printing table headers for($i=0; $i<$fields_num; $i++) { $field = mysql_fetch_field($result); echo "<td >{$field->name}</td>"; } echo "</tr>\n"; // printing table rows while($row = mysql_fetch_row($result)) { echo "<tr id='color'>"; // $row is array... foreach( .. ) puts every element // of $row to $cell variable foreach($row as $cell) echo "<td align='center' <font face='Arial, Helvetica, sans-serif' >$cell</td>"; echo "</tr >\n"; } mysql_free_result($result); ?> </body> </html> Currently my javascript code changes the entire row in the table, which is not I desired. How do I edit this script so that only values in particular CELL in a row e.g CELL 5, is changed and not the entire row? Thank you. I'm writing a script in javascript(actually a chrome extension) and I need an object that I can write to it like this(sorry, don't know how to explain it better) and then I convert it to string with format of json. Code: id[129].weekDay[6].hour[23] = 0 Here, id is an array, that each element in it contain another array(weeksDay) and in that array each contain another array(hour). The id indices are unlimited, for weekDay 7 and hour 24. I searched in google but i couldn't find what I wanted. Actually don't know the best keyword to search.(objects in arrays?) I don't know what exactly it is called, I can write it's declaration in VB.NET if that helps you. hie everyone plz i want to know how to make tabs using javascript.... i want to make tabs like this website http://traveline.idea-sys.net/CSP/Default.aspx?A=2&P=50 --> (M/S Darakum - Description / GalleryDeck / Plan) can anyone help me plz? Hi i need to use an equivalent of the php function array_count_values() Any help with that please cheers ewire Hello, I'm trying to create a textarea using Javascript, the function creates a textarea in IE, but it does not create that element in Firefox and chrome. JavaScript Code:- Code: function addRow()
{
alert("function start");
var table = document.getElementById('tableId');
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var cell1 = row.insertCell(0);
var textNode = document.createTextNode(rowCount + 1);
cell1.appendChild(textNode);
var cell2 = row.insertCell(1);
var textArea = zxcFormField('TEXTAREA','option1');
textArea.setAttribute("cols","20");
textArea.style.height = "42px";
textArea.style.width = "496px";
cell2.appendChild(textArea);
alert("function end");
}
function zxcFormField(tag,nme,type){
alert("2 function start");
var el;
try {
alert("In Try");
el=document.createElement('<'+tag+(type?' type='+type:'')+' name='+nme+' >');
}
catch (e){
alert("In Catch");
el=document.createElement(tag);
if (type) el.type=type;
el.name=nme;
}
return el;
}
When I call this function it goes in the catch block in Firefox and Chrome, the textarea is displayed and it disappears with a flash. I've banged my head against wall trying to figure this out. Thanks, Abhishek how to create a customizable event based calender i need to create a grid calender where user can edit the fields of the dates and he can block some dates ! is it possible please help to me i hope u will help to me thanking you reply soon I need to create an interactive map similar to the one on this site: http://viewers-guide.hbo.com/game-of-thrones/#!/map/ It is a map of a fictional area ( a real area but there are fictional buildings and characters on it) so I don't think google maps plugins are suitable. I don't want to reinvent the wheel, so if anybody has a good suggestion of a good jquery/javascript solution for interactive maps, please refer me to the relevant information. In other words, I need a map where by clicking the objects on the map, a popup window pops up with additional information about the 'scene' or a 'character'. In addition, the map will be dark from the beginning and more and more sites and characters will be revealed on it every week. Thanks for any tips! Hi, I am trying to work out a code where I can change the background colour of an HTML page via external JS page. Please note that I will be using different HTML pages with different colours so have to use Arrays. Here is what I have so far!!! here is my function, <script language="JavaScript"> var backColor = new Array(); backColor[0] = '#000000'; backColor[1] = '#111111; backColor[2] = '#222222'; backColor[3] = '#333333'; function changeBG(whichColor){ document.bgColor = backColor[whichColor]; } </script> ------------------------------------- What I need is to apply changeBG function to my HTML page using colour [0] Any help would be greatly appreciated! Hi sorry if this is a very simple question but how do I change the font color for certain elements of this javascript code that the client sees on their brower? This is a count down script and I have made the code red that I am trying to change - any idea how to do this? Thanks v much!!!! <script type="text/javascript"> var today=new Date() //Enter the occasion's MONTH (1-12) and DAY (1-31): var theoccasion=new Date(today.getFullYear(), 03, 21) //Customize text to show before and on occasion. Follow grammer below: var beforeOccasionText="until this event" var onOccasiontext="Event is Today!" var monthtext=new Array("Jan","Feb","Mar","April","May","June","July","Aug","Sep","Oct","Nov","Dec") theoccasion.setMonth(theoccasion.getMonth()-1) //change to 0-11 month format var showdate="("+monthtext[theoccasion.getMonth()]+" "+theoccasion.getDate()+")" //show date of occasion var one_day=1000*60*60*24 var calculatediff="" calculatediff=Math.ceil((theoccasion.getTime()-today.getTime())/(one_day)) if (calculatediff<0){ //if bday already passed var nextyeartoday=new Date() nextyeartoday.setFullYear(today.getFullYear()+1) calculatediff=Math.ceil((nextyeartoday.getTime()-today.getTime())/(one_day)+calculatediff) } //Display message accordingly var pluraldayornot=(calculatediff==1)?

I've tried sticking one of these lines in each of the conditional statements above, but realized that this line outputs the entire "Recently Popular" list, not just one item - so everything would end up being the same color still. I contacted the plugin author, who said that without hardcoding there's no way to get around this via the plugin, but that outputting it normally and running it through JavaScript might give me a way to apply CSS styling to it after it's been rendered. I'm not experienced with JavaScript, unfortunately... does anyone know how I can do this? Hi Im taking a course in web design and am working on a basic javascript page. I have a drop down box where you select a item and it opens a new window. How would I get the back ground color to be the same as the web page color (lightblue), what code would I use and where in my code would I put it?

I want to take data entered into the client, package it up as XML and use ajax to transmit it to the server. So far I've written my own class to create a simple xml document, but I'd like to do it properly with the inbuilt functions. |
