IE 7 is throwing a JS error and I can't figure out why (probably because I am new to JS). FF and IE8 do not throw any JS errors. The JS error I get looks like this:
Line: 42
Char: 3
Error: Expected identifier, string or number
Code: 0
URL: http://dev.emsketch.com/
I'm not sure which JS file this error file is referencing.
This works perfectly fine in firefox but i need it to work in IE the form variable names are all correct and everything but in Ie it keeps telling me when i submit the form that there is an Expected Identifier problem. Code:
When I used toFixed() method on a number, I thought that this method round a number to a specified approximation, but I got a surprising result, the number became string! 15.23689.toFixed(2) ==> "15.24". So does it convert the number into string?
I have a string stored in a variable var = "4.25 houses".
I would like to only extract the currency value, ie "4.25" from this. Is this possible? Also I would like to divide and multiply the new variable I get... does this number need to be converted or something?
What would be the best way to convert a month number to its corresponding string? I.e, 3 -> 'March'. Is there a builtin function or must I use a lookup table or something?
Now I need to convert a number(decimal) into a hex.string. I want to pass my blurit() two colors and have it start at color one and step its way to color two based on a determined step. I need to convert the new color to a hex string to be used to control the color of text. This is a rough example of what I am doing:
I'm trying to write code to swap images in a list. It's going to be a star rating control that highlights stars as you hover over a star. each image in the list has an onmouseover="highlight(this)" function and a unique id of 1 - 10.
Code: function highlight(star) { var num = Number(star.id); for (i = 0; i < num; i++)
[Code].....
I'm trying to convert the number 'i' used by the for loop to a string so it can be used by the getElementById() method to select the stars to be highlighted. But my intellisense is telling me there is a problem with that line. I tried
How can I check if a number exists by itself in this string by using the RegExp object?
var mystring = "11,111,01,011"; var match = "1"; var re = new RegExp( match ); var isFound = re.test( mystring ) );
Running this code returns 'true' which is not what I want since number one doesn't exist by itself. I need to use the "match" variable since it will change depending on user input.
I can only get it to work without variables in the expression. E.g.
Javascript variables are loosely typed: the conversion between a string and a number happens automatically. Since plus (+) is also used as in string concatenation, `` Ƈ' + 1 '' is equal to `` ཇ' '': the String deciding what + does. To overcome this, first convert the string to a number. For example:
How to check that a text field is a string not a number with javascript? Therefore,if the field is a number then I want to display a message that contain "You must enter a string". var str = champ.value; if (!(isNaN(str))) { alert("Vous avez saisi un nombre"); I tried the previous code but it does not work.
I'm looking for a way to grab a number from a string, although this number is not at either end of the string.
Here is the string in question: var el = "v4Function_Name('argument3')"
Here is a substring that returns the number ( the 3 ) successfully... var number = el.substring(el.lastIndexOf("ent")+3,el.length-2);
Seems very ineffecient to do it this way, and better to find a lean elegant way using replace(); How does one go about getting a value inside of a string with regular expressions? .. or is there a better way?
Here are a couple of the many expressions I have failed with...
var pat = /^[^ent][0-9]*$"/; var pat = /v4Function_Name('argument([^0-9]+)'/; var number = el.replace(pat,"");
I have a JS function which checks whether the directory field value entered starts with an alphabet or number only. Following is the code using regular expression.
function testpw() { var un = document.getElementById("dir").value; if (/^[^A-Za-z0-9]/.test(un)) { // only a-z0-9 allowed as first character

method which only accepts "/ktp/knas/" as the starting value and anything after that. ie it should accept /ktp/knas/*, rest everything is not accepted.
I have an Adobe pdf fill-able form field that requires a distance computation using javascript. One of the values needed in the computation is in the format of a string as feet - inches (for example: 4'-10"). I need to convert this into a number to use to complete a computation. Any code snippet or ideas on how to do this.
I am working on form validation, i want to validate "Name" input field value . I want that in "Name" input field no number can be input.

I used the command toUTCString() with a Date() object and now I would like to extrapolate the hour, to convert the string in number and to save it into a new javascript variable.Esampre:
