JavaScript - Help: How To Use Js To Assign Style Values To Table Cells?
Hello,
I'm Stephen Martin, an undergraduate Psychology student and researcher. Although I am a self-proclaimed tech geek, the extent of my knowledge ends abruptly at any sort of coding. I need help from anyone who is willing. The paradigm: I am currently investigating the decision making strategies in a particular population (I cannot reveal too much, lest our study be scooped by competing researchers in the field). The paradigm that we use is built through a package called MouseLabWeb (http://www.mouselabweb.org/). MLWeb basically provides an interface for researchers to create a html/php/js/css website that presents a grid (table). A small example is shown on the aforementioned website. The javascript functions allow each participant's events to be recorded, timestamped, and written to a MySQL database. This allows the researcher to know which cells the participant viewed, in what order, for how long, and ultimately to which decision the participant came. Additionally, the PHP/HTML creates the table, but the data within it is populated by the javascript. This is a blessing and a curse. Here is why. The problem: The javascript offered by MLWeb allows the cells to be randomized. This is necessary, because in such paradigms, counter-balancing is required, otherwise there would be order effects (e.g., people tend to automatically read from the upper left) that are not controlled for. So the order of the columns and rows are randomized, the data which is then placed into the html/php table. For the current study, we want the cells corresponding to particular types of information to be shaded differently. For example, we'd want cells that contain bad information to be dark, cells that contain neutral info to be grey, and cells that contain good information to be white. The problem is that setting these values (style="background-color: #XXXXX) only applies to the table as created by the PHP. It only affects the position, and does not consider the information that it is filled with. We want the information that a cell is filled with to dictate what background-color the cell is. Example of the problem (A,B,C are the different types of info, with the surrounding character implying shading) What we want: Unrandomized: [.A.] [|B|] [#C#] Randomized: [#C#] [.A.] [|B|] What the problem is: Randomized: [.C.] [|A|] [#B#] Again, thank you for reading this long post. I'm up for any suggestions! TL;DR The website uses PHP to render a table and javascript to populate it. Javascript randomizes the column and row order upon each visitation, thus randomizing the cells. How do I make javascript issue a background-color change to each cell according to the information that it is populated with. Similar TutorialsI'm having problems with selecting values from array. I have a dropdown box where you choose what fruit you want to buy. When selected the array should assign 2 values to that fruit. I don't know how to do that. Here's what I have.. I added comments. Javascript part: Code: <script type="text/javascript">
function Fruits() {
var selectfruit = newArray( //assigning values to fruit selected from dropdown box
newArray("Banana", 1, 1),
newArray("Apple", 1.2, 0.5),
newArray("Mango", 1.1, 0.9),
newArray("Orange", 0.1, 9.99));
var howmanyfruits = Number(document.getElementById("howmanyfruits").value); // how many fruits are you buying
var totalfruitsowned = Number(document.getElementById("totalfruitowned").value); // How many fruits do you already have
/* cash and coupons needed to buy fruits.
cash is cpst for 1 fruit.
coupons is cost for 1 fruit
cash_all is cost for all fruits you're buying
coupons_all is cost for all fruits you're buying
each fruits requires cash AND coupons to be bought. Cash and coupons are tied to the first values in Array.
Eg. If you choose Apple that value would be 1.2
The 'fruitsmaxtobuy' variable is not tied to the first value, but the second one in array.
If you choose Apple that value would be 0.5.
*/
var cash = Math.round(((totalfruitsowned * 0.51 * selectfruit) + 700)*10)/10;
var coupons = Math.round(((totalfruitsowned * 0.51 * selectfruit) + 850)*10)/10;
var cash_all = Math.round((howmanyfruits * cash)*10)/10;
var coupons_all = Math.round((howmanyfruits * coupons)*10)/10;
var fruitsmaxtobuy = Math.round((totalfruitsowned * 0.12 * selectfruit)*10)/10;
/*
Display Error if nothing is entered or if you forget to enter total fruits
*/
if (((howmanyfruits=="" || howmanyfruits==null) && (totalfruitsowned=="" || totalfruitsowned==null)) || ((howmanyfruits==Number(document.getElementById("howmanyfruits").value)) && (totalfruitsowned=="" || totalfruitsowned==null)))
{document.getElementById("cash").innerHTML = "Error";
document.getElementById("coupons").innerHTML = "Error";
document.getElementById("cash_all").innerHTML = "Error";
document.getElementById("coupons_all").innerHTML = "Error";
document.getElementById("fruitsmaxtobuy").innerHTML ="Error"}
else {
document.getElementById("cash").innerHTML = cash;
document.getElementById("coupons").innerHTML = coupons;
document.getElementById("cash_all").innerHTML = cash_all;
document.getElementById("coupons_all").innerHTML = coupons_all;
document.getElementById("fruitsmaxtobuy").innerHTML =fruitsmaxtobuy}
}

Hi! I am quite new to the world of JavaScript as I have done basic corse for it... and I have learnt that best way to understand it is to play around with it... but now I am stuck with on of the problem!! Problem: How can we assign text box input values by user to a variable and display that variable back on another element of the same HTML document(dynamically)... Conditions: The value has to be stored as a JavaScript variable only. No server-side script is to be used and has to be done locally. Please help!

Hi All, I tried to add links to open local xml files in browser in a dynamic table cells. I need help. I tried all ways but I think I miss something. I can open them without table just by document.write(xmlfile location). Here is my code. please help. function showResultsTable(searched, srchedname) { // get the reference for the body var mybody = document.getElementsByTagName("body")[0]; // creates a <table> element and a <tbody> element mytable = document.createElement("table"); mytable.setAttribute('id', 'resulttable'); mytablebody = document.createElement("tbody"); // creating all cells var mycurrent_cell = new Array(); for(var j = 0; j < srchedname.length; j++) { // creates a <tr> element mycurrent_row = document.createElement("tr"); mycurrent_cell[0] = document.createElement("td"); currenttext = document.createTextNode(j); mycurrent_cell[0].appendChild(currenttext); mycurrent_row.appendChild(mycurrent_cell[0]); mycurrent_cell[1] = document.createElement("td"); link = document.createElement("a"); link.name = ""+srchedname[j]); link.href = "C:\\AAA\\TestCasesList.xml"; mycurrent_cell[1].appendChild(link); mycurrent_row.appendChild(mycurrent_cell[1]); mycurrent_cell[2] = document.createElement("td"); currenttext = document.createTextNode(searched[j]); mycurrent_cell[2].appendChild(currenttext); mycurrent_row.appendChild(mycurrent_cell[2]); // appends the row <tr> into <tbody> mytablebody.appendChild(mycurrent_row); } // appends <tbody> into <table> mytable.appendChild(mytablebody); // appends <table> into <body> mybody.appendChild(mytable); // sets the border attribute of mytable to 2; mytable.setAttribute("border", "2"); } I am confuseif i use JS.. its should be in <head> but table should be in <body>.. how am i going to use that.. and put images in that table cell using JS??

This is my code. Now i have problems with the eraseImage and drawImage functions. They just don't work. Any help will be appreciated. Thank you Hey. so, I know how to add the row, and cells, I did that...except now I need to add properties to the cells (class, ID, onclick etc)...just wondering how I go about doing that. Here is what I have so far: Code: function add_new_proj(){
new_proj_id = prompt("What would you like the new Project Number to be?","xxx-xxxxx");
var table=document.getElementById('projectDisplay').insertRow(1);//creates a var which adds one row to the table
//the variables are finding the correct cell to enter the data into the new row (based on an array 0 based system)
var projectID=table.insertCell(0);
var ProjectName=table.insertCell(1);
var Client=table.insertCell(2);
var ClientProjectID=table.insertCell(3);
var delete_cell=table.insertCell(4);
projectID.innerHTML = new_proj_id;
ProjectName.innerHTML ="";
Client.innerHTML = "";
ClientProjectID.innerHTML = "";
delete_cell.innerHTML = "<span class='delete' id='$ProjKey-d' onclick='delete_edit_proj(\"ajax_modify_proj.php\",this.id)'> Delete </span>";
}
this is an example of what the cells look like (the ones that already exist, generated via PHP code): PHP Code: echo "<td class='projectTd' id='2tdName-$j' onclick='editTd(this.id);'> $ProjName </td>"; So yeah..I need the new cells to pretty much look like that >.< with a class, id, and onclick event. any help would be great! thanks Writing Table Cells and Switch Statements I am to create a function and purpose is to write blank tables cells to make up horizontal bar. function will have 2 parameters=(partyType and percent partyType parameter stores variables of D,R,I,G or L percent parameter store percentage rounded to nearest integer so I am to make a switch and break statements /commands then have to create a For Loop in counter variable goes up from 1 through value of parmeter increments of 1 heres the code I created for this one Code: function createBar(partyType,percent){ // script element to create blank cells
switch(partyType) {
case "D": document.write("<td class='dem'></td>");
break;
case "E": document.write("<td class='rep'></td>");
break;
case "I": document.write("<td class='ind'></td>");
break;
case "G": document.write("<td class='green'></td>");
break;
case "L": document.write("<td class='lib'></td>");
break;
}
var barText = partyType
for (i=0; i < percent; i++)
{
document.write(barText);
So what improvements should I make? should my loop be before everything? Thanks Hi, I'm having trouble with trying to access a selected value of a drop down menu in a table. I have menus in columns 3 and 4, named cred and grade respectively, from rows 2 onwards, and I'm using a function to access them. How do I access the value's for manipulating other variables? Here is what I have so far: Code: function f(tableID){
var len = document.getElementById(tableID).rows.length;
for(var i = 1; i<len; i++){
var c = document.getElementById(tableID).rows[i].cells[2].childNodes[0];
credits = c.options[c.selectedIndex].text;
}
}
Your help would be really appreciated Ok. I'm going to start by saying I'm a complete novice. I am having a hell of time finding specific codes for the things I need. I'm pretty impressive I've gotten this far. So I am trying to make a portfolio website, for myself, which has thumbnails on the left(which I'll crop in photoshop because it is easier for me than having to do any coding) which will make the main image on the right change. At the same time, I want it to change the text below to correspond to the current image. Now I have the images swapping alright, except that the thumbnails that have the onClick function in them won't sit inside the table I have inside the table. I don't understand why that happens. I can work around this, and just get rid of that table. Another problem is that even though I defined the collumns as each being 20%, they are not all the same size. I am using percentages so that the site will function regardless of screen resolution. Anyway, here is my current code. Ignore the image names, I'm just using what random images I have at hand while I test things out. Code: <html>
<head>
<script type="text/javascript">
function swap(image) {
document.getElementById("main").src = image.href;
}
</script>
</head>
<body>
<table width="80%" align="center">

So I am using JavaScript to make a table on a page and what I want to do is have the JavaScript create the table, and then allow the user to fill it with data. I have been able to make the JavaScript create the table, my question is how to reference the cells in my script that adds data to the cell. I want the users to be able to click a button an add data into different cells so i figured giving them each an Id and referring to that Id in the button is the best way to do it. How can I edit my code to give each cell a different Id? Or is there a better way of doing this? My table code looks like this (i have filled it with random data so it is not just a blank table). <code> <script type="text/javaScript"> window.onload = fnInit; function fnInit() { // Declare variables and create the header, footer, and caption. var oTable = document.createElement("TABLE"); var oTHead = document.createElement("THEAD"); var oTBodyam = document.createElement("TBODY"); var oTBodypm = document.createElement("TBODY"); var oTFoot = document.createElement("TFOOT"); var oCaption = document.createElement("CAPTION"); var oRow, oCell; var i, j; // Declare stock data that would normally be read in from a stock Web site. var heading = new Array(); heading[0] = ""; heading[1] = "Monday"; heading[2] = "Tuesday"; heading[3] = "Wednesday"; heading[4] = "Thursday"; heading[5] = "Friday"; var block = new Array(); block[0] = "8:30"; block[1] = "9:55"; block[2] = "11:20"; block[3] = "12:45"; block[4] = "2:10"; block[5] = "3:35"; block[6] = "5:00"; block[7] = "6:30"; var stock = new Array(); stock[0] = new Array(block[0],"88.625","85.50","85.81","99.54","55.46"); stock[1] = new Array(block[1],"102.75","97.50","100.063","49.54","55.46"); stock[2] = new Array(block[2],"56.125","54.50","55.688","99.54","55.46"); stock[3] = new Array(block[3],"71.75","69.00","69.00","99.54","55.46"); stock[4] = new Array(block[4],"71.75","69.00","69.00","99.54","55.46"); stock[5] = new Array(block[5],"71.75","69.00","69.00","99.54","55.46"); stock[6] = new Array(block[6],"71.75","69.00","69.00","99.54","55.46"); stock[7] = new Array(block[7],"71.75","69.00","69.00","99.54","55.46"); // Insert the created elements into oTable. oTable.appendChild(oTHead); oTable.appendChild(oTBodyam); oTable.appendChild(oTBodypm); oTable.appendChild(oTFoot); oTable.appendChild(oCaption); // Set the table's border width and colors. oTable.border=1; oTable.bgColor="lightslategray"; // Insert a row into the header and set its background color. oRow = document.createElement("TR"); oTHead.appendChild(oRow); oTHead.setAttribute("bgColor","lightskyblue"); // Create and insert cells into the header row. for (i=0; i<heading.length; i++) { oCell = document.createElement("TH"); oCell.innerHTML = heading[i]; oRow.appendChild(oCell); } // Insert rows and cells into bodies. for (i=0; i<stock.length; i++) { var oBody = (i<3) ? oTBodyam : oTBodypm; oRow = document.createElement("TR"); oBody.appendChild(oRow); for (j=0; j<stock[i].length; j++) { oCell = document.createElement("TD"); oCell.innerHTML = stock[i][j]; oRow.appendChild(oCell); } } </code> Hi I am trying to make all the cells within a table droppable spaces, using the scriptaculous library. However I am not able to do so, and I am not certain why. The table cells are creating within the javascript. I then try to apply the droppables to the table cells through iteration, through the function when the document loads. It does not seem to be working. The document accesses an external php page and has inline php within a div element. I am uncertain if by having the draggable elements instantiated within the php script, that this would be causing any problem, as I cannot see how this would be, the php draggables all appear to be corresponding to the css in the document. Any help with the droppables would be appreciated. I have set up a css class hover, so that when the draggable passes over the droppable the edges of the droppable area should be turning blue, but this is not happening. Not sure what the problem is.

OK. I'm super new to any kind of java script. What I want is a menu that, when clicked, changes the background color of a table cell to blue. When a different option is clicked, the current highlighted table should turn back to gray and the new selection should be blue. Well, I have all of that working. What I need now is just to have the first option start out highlighted and to become unhighlighted when another option is clicked. Any help would be awesome!!!! Thanks!!!!!! Code: <html>
<head><title>menu</title>
<script type="text/javascript">
var element = null;
function select(xx)
{
if ( element ) {
element.style.backgroundColor='gray';
}
element = xx;
xx.style.backgroundColor='navy';
}
</script>
<style type="text/css">
a {text-decoration:none; color:white}
a:visited {color:white}
a:active {color:white}
a:hover {color:white}
table#lay_menu {width:100%; margin:0px}
table#lay_menu td {text-align:center; width:20%}
.menu {text-align:center; background-color:gray; }
.start {text-align:center; background-color:navy; }
</style>
</head>

how can i get the number values from style atrributes. currently i have test_tree.style.top which would return 50px instead of 50, is there anyway i can take just the 50 as an integer
Hello. I need to make drop down box, with 2 statments: hide, show. And I need one table, that javascript set [style="display: none"](When the dorp dow is: hide) and [style="";](When the DDB is set to: show. Can any one help a little, please? Hello, I'm dynamically outputting the contents of a MySQL table using Python, to a HTML table, which users view (obviously) through a web browser. It looks great, but the problem is that I'd like users to be able to update these values. For example, I have the current value of certain fields in text boxes. I'd like users to be able to change those values, then hit a submit button or similar (ideally on-the-fly) to update the dB. I imagine javascript will need to pass values to a Python script, but I don't know what the best way to go about this is. The table is generated with a loop like so: Code:
# Python code embedded in a .psp file
cursor = db.cursor()
cursor.execute("SELECT from_name, from_address, project, orb_proj, app, tier, environment, network, security_zone, datacenter, server_type, num_servers, date, status FROM requests")
rows = cursor.fetchall()
for row in rows:
new_row = """
<td>%s<br></td>
... (line repeated for each column)
""" % row[0:15]
req.write(new_row)
Any ideas? Maybe this whole thing should be rewritten in something else. Thanks! I wish to get the values for the 3rd and 4th cell of each row where these contain drop down menus. I've tried various ways but my code doesn't seem to iterate through rows of a table. I can get the values for the first row, but not the rest. There's isn't a fixed row size for the table as the user will be able to add and delete them. I've put the values in separate arrays but instead of the array containing say [10, 20] it contains [10, 10] as it just duplicates the first row's values. Here's my code that I have so far: Code: function calculate(){
var len = document.getElementById(arguments[1]).rows.length;
var cMenus = [];
var gMenus= [];
for(var j = 1; j<len; j++){
for(var i = 2; i<arguments.length; i++){
var c = document.getElementById(arguments[2]);
var g = document.getElementById(arguments[3]);
cMenus[a] = c.options[c.selectedIndex].value;
gMenus[a] = g.options[g.selectedIndex].value;
}
a++;
}
<button type="button" onclick="calculate('text','course', 'credits', 'grade')">Calculate</button>
HTML Code up to the first dropdown menu: Code: <table id="course" summary="add/remove course details" width="350px" border="1">
<tr>
<td><input type="checkbox" name="tick"/></td>
<td><input type="text"/></td>
<td>
<select name="credits" id="credits">
<option value="10">10</option>
<option value="20">20</option>
</select>
</td>
</td>
<select name=....
I've tried adding j to the arguments or putting it in "[]" but nothing seems to work. I don't think the platform I'm using supports jquery, so help would be really appreciated for using javascript, thanks.
