JQuery :: Submenu From Array - Function ToggleOptions Takes 3 Variables - Target - Array - State
Feb 15, 2011
I am trying to understand somecode. I don't think I am understanding everything correctly. Can someone confirm or add to my understanding?
Here is the code, below is my explanation:
- CODE 1 - is saying if the the class subnav_dd is called on an anchor tag on a li, then make the function in the if statement "live". (Live in a sense binds the function to the condition, but unlike bind it allows the condition to be used more then once. ) So if the class subnav_dd is the parent, and has a class of .dis then prevent anything below it from firing. CSS - If code 1 is true, then I will only get the first li to fire, the remaining ones will not.
- CODE 2 - This one is a little tricky. Function ToggleOptions takes 3 variables (target, array, state). The condition is if the div subnav + target have siblings, then check to see how many siblings are there. Put the amount of siblings into an array, then check the state of each sibling. I don't completely the rest of it.
I think if the div subnav is called and something is found in the array then the class dis is either added or removed. Then what? I don't understand why I still need the else that adds a class to #subnav_ +.target
I'm having a hard time getting my head round it again. I know it could be more efficient in jQuery, but I'd be happy just to get it working, with an extra variable, in straight js.The function takes an array and progressively hides each element at constant interval, in this case 50ms:
function hide_50(arrayA,visibility,current) { if ( current == null ) current = 0; var arrayB=(typeof arrayA == 'string')? arrayA.split(',') : arrayA;
how to accomplish this. In my website, I would like the user to input text into a single or multiple textbox(es) and then have the contents of the textbox(es) stored to either a variable or an array. Then I would like to have that variable/array compared to other arrays. Basically, the user is searching for items in a database. The user can search for as many or as little items as they want. Then the item(s) will be compared to multiple arrays to find out if what the user wants is in the database.
So for example, let's say the user is searching for recipes that have all or part of these ingredients: chicken, broccoli, lemon, honey. So, there would have been a total of 4 textboxes...one for each ingredient. These ingredients are stored to an array..lets call it ingredient(). In the database of recipes, each recipe has its own array which includes the ingredients needed to make the recipe, we'll call them tag1(), tag2(), and tag3(). Now, I want the array, ingredient(), to be compared to each of the "tag" arrays to see if any of the "tag" arrays include exactly match the ingredient() tag in part or in whole. Is this possible?
In the exercise I have 5 elements (lets call them input fields), 3 of which I have given a class of 'red' to. What I can't figure out is how I select just the input tags with the class='red' attribute on them by using the getElementsByTagName. I understand that getElementsByTagName puts all the elements into an array, but how do I target the ones just with the red class?
I'm sure there is a way of doing it using the className property but I can't seem to get anything working?
How can I go about setting a number of variables using a table which will have the variable names to be declared in one table. The data to be assigned will reside in another. As an example, I know this assignment works:
var nam0 = tab[0] var nam1 = tab[1] var nam2 = tab[2] .. .. ..
What I would like is to use two tables
var namtab = ["nam0","nam1","nam2"] var tab = ["va0","val1","val2"]
Then using a loop, assign the variables so that I may address them by name "nam0" rather than namtab[0].
var nametab = ["nam0","nam1","nam2"] ** also tried w/o the quotes for(var i=0;i<3;i++) { var nametab[i] = crumbs[0];
We are using JQuery for one of our software projects, and it's a very nice library. It's making things far easier. We are also using the Validation plugin, which is working wonders for form validation.However there's one wrinkle that we have not been able to figure out.Is there any way to run a function before the validation takes place?We have help text displayed in some of our text inputs and text areas,which are cleared onFocus (and restored onBlur if the user has not entered anything). We would like to clear those help text before validation is run, so that we don't get any false validations based on the help text, rather than the actual value of the field, which is blank.
How do I get this function to return an array? It seems that outside function(xml) the array is not seen and at the same time return inside function(xml) does not make the GetNumbers function return anything either.
Code:
function GetNumbers(db_id){ $.post("get_numbers.php",{ id: db_id,
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 have this C# code that is connecting to database and creating a array(list)
Code:
I'm trying to pass it to a javascript function so I can then pass it to a silverlight page so I was able to create this easy javascript that show a aleart box on startup of the list(array)
Code:
But I want to do something like this and can't get it:
Once again I call on the gurus after banging my head against the wall for a few hours. I use .clone to clone some elements then I get the various values in an array. All that works fine. However, I want to total up the array so I can validate the total against another value.In the code below if I put the x array in the sum such as sum(x) and alert(quantityTotal) it shows 4 as expected. If I simply alert(quantities) I get 3,1 however, if I sum(quantities) and alert(quantityTotal) I get 013 instead of the expected total of 4 I'm baffled (as usual..haha). Must be something simple I'm missing.
var quantities = [];//quantities array $.each($('.quantity'), function() { quantities.push($(this).val());
I am really hoping someone is willing to take the time to read this post and take a minute to take a look at my code. What is happening is there are some matches for a script I made and then an area for segments during an event. If you notice on the segment part of the form is that there is a dropdown that asks for where in the event that segment needs to go. With the Introduction or the different numbered matches. What I need to happen for a subArray I need it to take the introduction, all the matches, and all the segments and order them accordingly. With the introduction first, the matches in order based off there match number and then the segments in between the introduction or matches based off the user's input.[URL]..
I am working on a page where the user will select a location from a dynamically generated dropdown list. I was able to create the php multidimensional array (tested and working) from a MySql database using the users information at login, but I'm having problems converting it to a javascript multidimensional array. I need to be able to access variables that I can pass to a number of text fields within an html form.For instance, if a user belongs to a company with multiple addresses, I need to be able to let them select the address they need to prepopulate specific text fields.
This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code: var flag; for (i=0;i<=pdfs.length-1;i++) { flag = 1; for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.
I am building a customised javascript prototype to sort an associative array on the array key (in ascending order). Basically, I am separating the array keys into a separate array and then using .sort() to sort the keys and then reassembling the original associative array elements according to the sorted keys array.
The sorting works ok except that when I run the test code below, the outputed sorted associative array has an extra element at the end of the array whose key is the name of the prototype function and the value for that element is the function code itself. Obviously I am misunderstanding something about associative arrays or how javascript prototypes work.
I want to have a simple code such that some data is stored in array. When we create a search box it has to give suggestions from the data stored in array.
This is the first question I couldn't find answered by Google! No doubt the answer is out there, but...
So I have a function that is being passed an array of nodes: some of them plain vanilla DOM nodes, (say, those created by document.createElement), others are jQuery nodes (say $("<div></div>").
What's the best way to determine if a node is of each type? I can obviously look at the node contents, but I wondered if there was a "best practices" here?
I'd like to reorganize the third, fourth, fifth and sixth, as well as any elements thereafter in an array in random order:
var a = new Array('first','second','third','fourth','fifth','s ixth','etc')
In other words, the first, second and third element should remain in position 0, 1 and 2, while the fourth, fifth and sixth, etc. should appear in random order.
I'm trying to grab values from a set of arrays based on the value returned by my select box.
**Caveat - this is not an area I have any real experience with**
My arrays look like:
Code JavaScript:
I then need to test for each, then associate with one of my fees arrays, then grab each of the values in the array and write those values to elements within my page.
I'm then doing this to evaluate for each degree
Code JavaScript:
I need to first figure out how best to import all of these 60+ arrays and then in each of my conditions pull out each value and write to my page.
There is a unique 1 to 1 relationship between each degree and array so I can't consolidate as the values for each degree differ slightly.
