Code JavaScript:
if(document.getElementById("applicable_us_sales05").value !== ""){
var applicable_us_sales05 = eval(document.getElementById("applicable_us_sales05").value);
} else {
var applicable_us_sales05 = 0;
}
Is there a shorter way to write that?
I am totally new to jQuery and no good knowledge on javascript. However, I was assigned a task, to convert a javascript program to jQuery due to compatibility problem on browsers like Chrome and Safari. My program originally use javascript xmlDoc.load('....') to read XML file, and then use document.write statement to write html tables on client side. Something like this (the sample below may got lots of syntax problem as I jut want to show the major part):
Code:
document.write('<TABLE >');
var y=x[0].getElementsByTagName('NoOfRows');
for (i=0; i<=noofrows-1 && i<=y.length-1; i++){
document.write(' <TD>');
document.write(z[j].getElementsByTagName('RecordDetails')[0].childNodes[0].nodeValue;
}
Now I changed to use jQuery, I can read the XML file elements. However, when I try to write the table, it failed:

Why doesn't this work? The input field doesn't show up at all. I know I'm just missing something really simple here.
<script type="text/javascript">
day = day.getDay()+1;
month = day.getMonth()+1;
year = day.getYear();
newdate= month + '/' + day + '/' + year;
document.write('<INPUT name=Date value='+ newdate + '>');

I have a client that has ads on her website that really slow down the site. These ads are called by an off site javascript file and I want to use a jQuery(document).ready or similar method to call these files after all of the site content has loaded. But these files contain document.write functions to add more javascript files. Since I want to load the files after everything else has loaded, this in turn makes the page blank and then loads the ad. Is there a way to position where document.write will write to?
View 1 Replies View RelatedI'm pretty new to JavaScript and am having a problem. I thought what I am doing should work but it isn't.
Basically I have a form that people can put a quantity into. e.g. A, B, C.
I have a JavaScript function called comput that assigns values e.g. A = 5, B = 7, C = 9. Here is the start of the script:
<script language="JavaScript"><!--
function compute(form){
var A = form.A.value * 5;
var B = form.B.value * 7;
var C = form.C.value * 9;
I then declare a variable to add them up:
var ans = A+B+C;
return;
}
</script>
This part of the script works fine. Now I want to write the ans variable. So I use:
<script>
<!--
document.write ("Your total is "+ans+"")
// --></script>
But it isn't working. Any ideas?
I'm working on a website that will basically embed a widget/frame sent by a handler into a user's current page. The user basically adds a script tag to where they would like the HTML to be. The script tag has their settings and is basically a document.write that calls all the code that we want displayed.So here's my problem. We have a map that we need to add in a specific section, and to get the map we have to call another script tag. So we end up having a script tag (map) embedded in another script tag (the code for the widget/frame) or we end up having to document.write inside a document.write.
Now this works just fine and as expected in Firefox, Safari, and Chrome. However, Internet Explorer and Opera wait until the first document.write is completely finished before calling the embedded one. Of course the problem with this, is that it takes the map out of the document's flow and just appends it to the bottom left of the page. Since the rest of the page has already been called, there's no way to move the interior "map" script.Any ideas? Basically just trying to figure out how (if even possible) to render an embedded script tag in Internet Explorer and be able to place it properly. I've tried everything that I can think of, including AJAX and Google's unescape script.

I am reading the ECMAScript specs trying to figure out if the next

I think the above code may only be legal as an expression and not as a
stand alone statement. Would this make the above a bug?
Douglas Crockford's JSLint will choke on the above line of code and
stop parsing. All the browsers seem to accept it as ok and work as I
expect: the returned object just doesn't get assigned to anything.
The time I have used a line like the above is when the constructor has
side effects and the "class" keeps track of all its instances.
Any ideas what is right or wrong in this case?
I have several text fields on page that I would like to make calculations based on if there is a number input in one of the fields.
So, if the price field is populated, the sale price field would populate using a function to do the calculation.
Now, how do I write the code for this to occur? I know how to get the function to fire based on clicking a submit button, but not sure how to do it simply based on a number keyed into the one field. Is this possible and if so, how?

I remember using if statements with null in it. For example, at one

document.write(value)
However, this script causes an error in any browser. Why can't it
correct the value like it should?

I have a two fold question:1) Why would my while statement not be workingI have cleaned up my code a little (although not perfect) but my while statement is not behaving, it does not output any numbers on a console.debug (using google chrome, or any other browser for that matter) which from my understanding it should?and 2) Slightly out of the remit of this forum I suppose, but this code is quite lengthy and I know there are ways to make this more efficient I just dont know what they are?

I need to give two separate alerts depending on what the user clicks when they click the "Submit" button. I am using a confirm box. If they click "OK" it thanks them for their order. If they click "Cancel" it should go back to the form. I have written the code that I thought would work but it will not.
