Is it possible to use splice() with a variable index. I understand that splice(1, 1) means start at index position 1 and remove 1 item. However, I want the index position to be a variable, since I don't know the actual index number of the item to delete at runtime. Is this possible?
thta should of out put me "hello world" as it is what it is in array but it does not as there is 422 there That's my ID from database, and I gotta use itNow, if I change that ID to something in letters say to "i" then everything is fine. ex
PHP Code:
json_data_object.i.name
That one would work, but then I have to chnge JSON string thta pulls data from DB and i cant really do that...So the question is how can I make 422 (numbers) works the same way as just string values in the array/object tree?
I'm trying to figure out how I replaces/removes parts of text in string in realtime using jQuery. This is what I got now:
PHP Code: $str = 'This is a <b>test</b>. Its not going well!'; echo '<div class="element">'; echo '<span>'.$str.'</span>'; echo '</div>'; echo '<p>Remove</p>'; Code JavaScript: $('p').click(function() { $('.element span').each(function() { var test = array('<b>','</b>','well'); //var test = 'not'; console.log($(this).text()); var text = $(this).text().replace(test, ''); $(this).text(text); }); });
The problem: As above nothing happens. If I use the var test = 'not'; instead of the array part it works except it also removes the <b> tags? How do I get the array part to work and why is it removing htmltags when executed?
trying to write a function where i can pass an array and string and replace the value in return. i.e
var inputStr = "010203040506070809111213141516171819";
i want to pass this value in function and replace each number (number ranges are 01-09 and 11-19 only) i.e if i pass 01 want to replace that with A,02 with B etc.. so problem is i would pass input string and pass back as string after replacing those values by running through the below function. wrote the following,cant seem to split my inputStr into 01 02 etc tried splice and split no luck :
<script type="text/javascript"> var str="Welcome to Microsoft! Microsoft Microsoft"; var stringToBeFound = 'Microsoft' var ReplaceString = 'site' document.write(str.replace(stringToBeFound , ReplaceString )); </script>
My problem is im trying to use string.replace that is not case sensitive and replace every string found. I could use regular expression with it but my stringToBeFound is a dynamic variable im getting it from my database

Currently I'm trying to create a menu with a mouseover effect on a link, which causes an image to display. All images are positioned on the same place, so the optical effect is that one image changes all the time. To achieve this I created an unordered list with the links / items in it, and I created a div with the (corresponding) images. On a mouseover event over a link, the index number of the current li element is stored in a variable, and I want to use that variable to select the corresponding image.
(So <li> index:2 corresponds to <img> index:2) So in 'human language': on mouseover of li { var indexNumber = li.indexnumber change class of img[indexNumber] }
But I can't get it to work. I managed to store the 'current' indexnumber successfully in a variable: var indexNumber = $("li").index(this);
But I can't use the variable to select the corresponding <img> I tried: $('.slidemenuImgbox img:eq(indexNumber)').addClass('slidemenu_show'); But nothing happens
However when I do: $('.slidemenuImgbox img:eq(1)').addClass('slidemenu_show'); The image with index:1 is changed. How to use a variable in :eq() To see a 'live' example (With no images changing): [URL]
I want to create an associative array dynamically pulling the index values from an array (propertyArray); Associative array is created inside create function and then returned. But after it is returned, I cant use index names to retrieve values. It returns undefined as below code shows.
Code JavaScript:
var propertyArray=["a","b","c"]; function create(){ var array=[];
I ran into a problem that I could not fix myself, I am trying to replace a string with another string, the replace lines look like this:
Code: var word = document.getElementById("word").innerHTML; document.getElementById("word").innerHTML = wordd.replace(/B/g, '<span class="style106">B</span><span class="style107"> </span>'); It works just perfectly if left alone, but I need to replace every letter inside this string, adding those style and span tags around each and every letter. So if I add another line to this code, like this:
If I know that apple exists in above list.How to get index of whole string from the list.Like apple should have the index 1, ball should have 2 and so on.
Let's say I have a string, something like this: sadasd4assadasd8ssssda5asadasd3asdasdasd8dsdsd

I have a string like this: $433.00 As you can see it's a price with the Dollar sign, I need to convert that to an integer. How would I do that in Javascript?
I'm triying to convert a string (0000, 0001, 0002, 0003,0004,0007, ..., ... )in INT. Betwen 0000 and 0007 theres no problem. But the 0008 is converted to 1. I'm using
So my question is, if the above behaviors are the same?? If string is a number, and compare with another number, it will be the same behavior as compare 2 numbers?
In this case, it is comparing 2 strings that are numbers, so they are string comparisons here. correct?
if ("123" > "33") will return true
In this case, "33a" is not a number, that's why when it compare with another number, it always return false. correct?
I'm developing a web app and I want to validate a users input on a form. I need a regular expression to validate a string which must begin with a letter (i.e. A-Z or a-z) and must have 5 numbers (0-9) after it....
I'm refering to an entry in an array by it's string key, as in foo["bar"]. Is there a way to get the numeric index of that array without iterating through the entire array?
What I need to do is find the "next" or "previous" entry in the array, but the keys are strings, instead of numerical indeces.
