JavaScript - Optimal Method Of Applying Css With Javascript
I'm designing a page that uses javascript+css for enhanced interaction. However, if javascript is disabled, I'd still like the page to be functional, albeit less fancy. Likewise, if css is disabled, it still needs to be functional. Finally, if both js+css are disabled, the page will be quite bare but still usable.
For example, I use javascript to set a css style that hides certain panels of content. JS is used to toggle these and all is fine. If JS is disabled, then the css isn't applied, and all the content is visible (though not too pretty). If CSS is disabled, the inline CSS applied by the JS works fine. Finally, if both are disabled, all the content is visible. I'm wondering what's the best way to do this. Currently, I set the styles like this in the js file: Code: function initialize() {
// set styles, for example:
document.getElementById("panel").style.display = "none";
}
var onloadFlag = false;
document.onreadystatechange = function() {
if (!onloadFlag) {
onloadFlag = true;
initialize();
}
};
// for older browsers
window.onload = function() {
if (!onloadFlag) {
onloadFlag = true;
initialize();
}
};
The problem that sometimes comes up is I see the "fallback" styles briefly, before the JS kicks in and applies the enhanced css. How can I avoid this? Similar TutorialsI have some javascript which applies alternative row colors to a table and also gives you a highlight effect when you mouseover the rows. However, the problem I have is that it applies to every table on my page, I only want it to apply to a specific table in the html file (I'm using frontpage), not all of them How would I go about doing this? The code is below, it has a bit of styling at the top before the javascript. <style type="text/css" media="all"> table.altsrowtable { width: 90%; margin: auto; border-collapse: collapse} td { border: 1px solid black; cursorointer;text-align:center} /* row 1 */ tr td { background: #edf3fe; } tr:hover td, tr.ie td { background: #e1e1ff; } /* row 2 */ tr.bis td { background: #D9ECFF; } tr.bis:hover td, tr.bisie td { background: #e1e1ff; } /* selected row 1 */ tr.sel:hover td, tr.selie td { background: #edf3fe; } /* selected row 2 */ tr.selbis:hover td, tr.selbisie td { background: #D9ECFF; } </style> <script type="text/javascript" span="altsrowtables" div="altsrowtable" id="altsrowtable" class="altsrowtable"> var IE = false; /*@cc_on IE=true; @*/ var r; function setRows(){ r = document.getElementsByTagName('TR'); for(var i=0;i<r.length;i++) r[i].className = (i/2 != Math.round(i/2))? '':'bis'; } function selectRow(aRow,add){ var c = aRow.className; if(add) setRows(); var b = aRow.className; if(IE) aRow.className = b==''? 'selie' : b=='bis'? 'selbisie' : c=='selie'? 'ie' : c=='ie'? 'selie' : c=='bisie'? 'selbisie' : c=='selbisie'? 'bisie' : ''; else aRow.className = b==''||c==''? 'sel' : b=='bis'||c=='bis'? 'selbis' : c=='selbis'? 'bis' : ''; } // roll-over (only for IE) function roll(what) { var c = what.className; what.className = c==''? 'ie' : c=='bis'? 'bisie' : c=='bisie'? 'bis' : c=='selbis'? 'selbisie' : c=='selbisie'? 'selbis' : c=='selie'? 'sel' : c=='sel'? 'selie' : ''; } // fire on loading onload= function() { setRows(); for(var i=0;i<r.length;i++) { if(IE) { r[i].onmouseover = function(){ roll(this); } r[i].onmouseout = function(){ roll(this); } } } } </script> <style type="text/css"> table.altrowstable { font-family: calibri; font-size:11px; color:#333333; border-width: 1px; border-color: #C0C0C0; border-collapse: collapse; } table.altrowstable th { border-width: 1px; "background-image:url('QP Header.png');" border-style: solid; border-color: #C0C0C0; font-size:12px; font-style:bold; } table.altrowstable td { border-width: 1px; border-style: solid; border-color: #a9c6c9; } </style> Thanks Sean would it be better to place the javascript into a .js file or just place the js code somewhere else in the html? How should it look? Code: <div style="width: 225px; height: 155px; float: left; height: 16px; background-color: #000000; color: #FFFFFF; margin-left: 0px; margin-bottom: 0px; font-size: small; padding-left: 0px;">
<img alt="" src="images/news.png" height="16" width="222" /><div style="width: 225px; height: 155px; float: left;"><script type="text/javascript">// <![CDATA[if(document.layers){document.write('<ilayer id="ns4div" width="'+swidth+'" height="'+sheight+'" bgcolor='+sbcolor+'><div id="ns4div1" width="'+swidth+'" height="'+sheight+'" onmouseover="sspeed=0;" onmouseout="sspeed=rspeed"></div></ilayer>')}

I am still wanting to do is the same thing, but with drop down menu's (SELECT) instead of INPUT. Is there anyone clever that can think of a solution? I'm still trying to work on it, but haven't thought of anything up yet.. Hey peeps, I'm trying to use wget to access this website that uses javascript. The website is from my work. Basically I made a program that parses information from our payment page. It tells me how much I am being paid for the month. Anywho, the variables on the page are in javascript, and thats one language I'm not proficient at. I need to change the month that it gets the pay for. The default is the current month. But it can be changed to last month, and from the code I can tell that something has to be changed from "THIS_MONTH" to "LAST_MONTH", but I'm not sure how to properly do it. Posted below is the source code from the website. Please let me know how I can change that without actually having to click the button to change the scope to last month. And also, is there any way to change this in the post method, or any other method that wget uses? I only included the parts I thought could be relevant. Thanks guys! BTW, I think it pertains with g_FiltersMenuStr Code:

Hi , I am inserting an image into a span tag by click on button and resize the image using resize_image_height_weight function. I am using two function to do this task. setImage setImage_w3Validation setImage function resize the image but fail on w3validation on my webpage( As per w3c there is no attribute onload for image tag.) To fix out this issue I am using setImage_w3Validation function which pass on w3validation but unable to call resize_image_height_weight function. My purpose is to resize the image. Kindly suggest me how to do it? <html> <head> <script TYPE="text/javascript" language="javascript"> function resize_image_height_weight(id, hgt, wdth){ //alert(id); Obj=document.getElementById(id); myImage = new Image(); myImage.src = Obj.src; var heights = myImage.height; var widths = myImage.width; // alert("Height=>" + heights + " Width=> " + widths); if(heights > hgt || widths > wdth) { if(heights > widths) { var temp = heights/hgt; var new_width = widths / temp; new_width = parseInt(new_width); heights = hgt; widths = new_width; } else { var temp = widths/wdth; var new_height = heights / temp; new_height = parseInt(new_height); heights = new_height; widths = wdth; } } Obj.height = heights; Obj.width = widths; } function setImage(){ document.getElementById("IM0").innerHTML ="<center><img src=\"http://www.google.co.in/intl/en_com/images/srpr/logo1w.png\" id=\"img1\" alt=\"\" height=\"125\" width=\"125\" onload=\"resize_image_height_weight('img1',125,125);\"><\/center>"; } function setImage_w3Validation(){ document.getElementById("IM1").innerHTML ="<center><img src=\"http://www.google.co.in/intl/en_com/images/srpr/logo1w.png\" id=\"img2\" alt=\"\" height=\"125\" width=\"125\"><script type=\"text/javascript\">document.getElementById('img2').onload = function(){resize_image_height_weight('i12',125,125);};<\/SCRIPT><\/center>"; //I wanna to do the task using this one function to resize img for w3validation } function clear_page(){ document.getElementById("IM0").innerHTML =""; document.getElementById("IM1").innerHTML =""; } </script> </head> <body> <div class="img3"><span id="IM0"></span></div> <div class="img3"><span id="IM1"></span></div> <input type="button" name="btn1" value="Image Onload W3C Fail" onclick="setImage();"> <input type="button" name="btn2" value="Image Onload W3C Pass" onclick="setImage_w3Validation();"> <input type="button" name="btn2" value="Clear" onclick="clear_page();"> </body> </html> Why is the callwhy is the slice method only a method of an Array instance? The reason why I ask is because if you want to use it for the arguments property of function object, or a string, or an object, or a number instance, you are forced to use Array.prototype.slice.call(). And by doing that, you can pass in any type of object instance (Array, Number, String, Object) into it. So why not just default it as a method of all object instances built into the language? In other words, instead of doing this: Code: function Core(){
var obj = {a : 'a', b : 'b'};
var num = 1;
var string = 'aff';
console.log(typeof arguments);//Object
console.log(arguments instanceof Array);//false
var args1 = Array.prototype.slice.call(arguments);
console.log(args1);
var args2 = Array.prototype.slice.call(obj);
console.log(args2);
var args3 = Array.prototype.slice.call(num);
console.log(args3);
var args4 = Array.prototype.slice.call(string);
console.log(args4);
Core('dom','event','ajax');
Why not just be able to do this: Code: function Core(){
var obj = {a : 'a', b : 'b'};
var num = 1;
var string = 'aff';
var args = arguments.slice(0);
var args2 = obj.slice(0);
var args3 = num.slice(0);
var args4 = string.slice(0);
//right now none of the above would work but it's more convenient than using the call alternative.
}
Core('dom','event','ajax');
Why did the designers of the javascript scripting language make this decision? Thanks for response. This is my first post. I am reading "Javascript The Good Parts" ~ The Method Invocation Pattern Page 28 and tried this, var myObject= { value:0, increment:function(inc){ this.value+= typeof inc==="number" ? inc:1; } } myObject.increment(2); alert(myObject.value); but alert(myObject.value); is returning a value of "2", when it should return "3". Can someone help?

I am using javascript for adding and removing rows from table as per user require ment like if we press ADDROW button it adds extra row to table and if we pressREMOVEROW it delets the last row.. Now i want to access the data from textbox like this.. var crpt = document.getElementById("itrtr2").value; //no. of rows for(var k=1;k<=crpt;k++) { qtyc = document.getElementById("txtRowc3"+k).value; unit_pricec = document.getElementById("txtRowc5"+k).value; alert('QTYC:'+qtyc+' UPC:'+unit_pricec); cttl = qtyc * unit_pricec; document.getElementById("txtRowc6"+k).value = cttl.toFixed(2); csbttl = csbttl + cttl; } document.getElementById("subttlC").value=csbttl.toFixed(2); it shows the value of textRowc3i in qtyc in alert box but also givs error document.getElementById("txtRowc3"+k) is null.. I tried for this but problem is not solved please help... Thank You... I'm trying to write a method called printPowersOfN that accepts a base and an exponent as arguments and prints each power of the base from base0(1) up to that maximum power, inclusive. For example, I'm trying: printPowersOfN(4, 3); printPowersOfN(5, 6); printPowersOfN(-2, 8); which should give me: 1 4 16 64 1 5 25 125 625 3125 15625 1 -2 4 -8 16 32 64 -128 256 but I only get: 64 15625 256 Here's my code: Code: public class Powers {
public static int printPowersOfN (int base, int exponent) {
int answer = 1;
for (int i=1; i <= exponent; i++) {
answer*=base;
}
return answer;
}
public static void main(String[] args) {
System.out.println(printPowersOfN(4, 3));
System.out.println(printPowersOfN(5, 6));
System.out.println(printPowersOfN(-2, 8));
}
}
What should I change so that it does all of the powers? i want to write a code which would prompt the user for his first name and last name with space in between them.The full name must be entered in the same prompt box.Using the charCodeAt() method i wanna test the first character of the user's first name as well as last name.If the first character of first name is in lowercase then it should alert the user as "first name must start with uppercase".And if the first character of second name is in uppercase then it should alert the user as "second name must start with lowercase". ..plzzzz help me and give me some code for this..i m a beginner in javascript..
Have the code check that the statement has at least one character. You can do this by using the trim method to remove spaces from the beginning and end, and then checking the length of the trimmed string. If there are no characters, the response should tell the user to enter something. For example, a possible statement and response would be: Statement: Response: Say something, please. Could someone help me with this? I'm not sure how to make it check to see if the user input has 0 characters. I'm a newbie of JS and don't know if I have got the right terms in my question. I want to lowercase all the arrays: Code: <script>
var txt = [
["Cats","Dogs","Rabbits"],
["Fish","Bones","Carrots"]
]
document.write(txt[0][1] + " love eating " + txt[1][1]);
</script>
I know I can do something like this: Code: document.write(txt[0][1].toLowerCase() + " love eating " + txt[1][1].toLowerCase()); // or var txt1 = txt[0][1] + " love eating " + txt[1][1]; document.write(txt1.toLowerCase()); But if I will loop through all the arrays and print them out, I am bothered with appending .toLowerCase(0 after each array one by one, so is there any way to bind that method at one go? I hope my question is understandable. Maybe I've used wrong terms of JS. Thank you. So I'm new around here, and to web dev in general, but I've got a (hopefully) short question. I am trying to call a function (nextMonth()) every second from the time that the cycle method gets called, until it is called again. As of now I am trying to use setInterval, (and I previously tried with setTimeout and using a callback argument but maybe I wasn't doing that properly). The problem is that after running the cycle() method for 5 or 6 seconds, the entire browser freezes up and you have to kill it and restart it. Here is my code as of now: Code: function cycle()
{
if(CYCLEINT != null) //STOP THE CYCLE LOOP
{
window.clearInterval(CYCLEINT);
CYCLEINT = null;
document.getElementById("cycle").innerHTML = "Cycle Months";
}
else //LOOP IS NOT RUNNING, INITIATE AND CONTINUE INTERVAL.
{
CYCLEINT = self.setInterval("nextMonth()", 1000);
document.getElementById("cycle").innerHTML = "Pause";
}
}
function prevMonth()
{
var dVal = $( ".slider" ).slider( "option", "value");
if(dVal > 1)
{
dVal--;
$( ".slider" ).slider( "option", "value", dVal );
refresh();
}
}
function nextMonth()
{
var dVal = $( ".slider" ).slider( "option", "value");
if(dVal < dateMax)
{
dVal++;
$( ".slider" ).slider( "option", "value", dVal );
refresh();
}
if(CYCLEINT != null && dVal >= dateMax)
{
cycle();
}
}
