I want to remove items in an array by passing index values. The index values may have 1 or more values. For example, i have the following array
Code:
var arr1=new Array("aa","bb","cc","dd","ee","ff");
var index = new Array();
index[] = 3;
index[] = 5
[Code]...
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=[];
[code]....
In our ordering system, we have to type in various values for several items at a time. This means in one single form, for one order, we could be typing in a batch number 4 or 5 times. I can valiadate this easy enough with Javascript when there is only 1 line. But what if there is more than 1?
With PHP you add [] to the end of the form element's name. But how do I get javascript to work with this?
Code:
Basically, the batch number, expiry date and pallet/box number is mandetory. If they arn't entered, it needs to fail (return false). It doesn't seem to be doing anything, just moving on to the next part which is checking other parts of the form which isn't repeated.
Is there a built in method to remove empty array elements?
View 2 Replies View RelatedI have a phpsubmission form that I am passing the values to another php page that inserts the field values from the submission form. So I added a JQuery function on my submission page like so.
function addComplaint()

$.ajax({
type: "POST",url: "http://oscscar02/functions/addComplaint.php", dataType: "html",
data: $("#caseNum, #formNum, #calendar, #invoice, #prodID, #serial, #prodReturn, #compText, #hazardLevel,

The problem is#caseNum is actually amulti value select list. Now I know how to work with this using straight up php like so:

Over in this thread, someone suggested a solution to an issue I was having when attempting to send multiple values per select box to a php file. You can review my original post here for reference:
[URL]
The problem is, when I change my form names to be arrays (i.e. age[] vs. age), it broke my Ajax script. I copied the original script from w3schools, and I don't really know much about javascript/Ajax to know what it is that I need to do to fix this.
Here is my Ajax script:
Code:
<script type="text/javascript">
function showResult(name,age,gender,ethnicity,facility)
{
if (name=="" && age=="" && gender=="" && ethnicity=="" && facility=="")
[Code]....
Now, when I leave my field names without the [], the script works MAHvalously. However, as soon as I add in the [] to the field names, and also update the vars to be age[].value instead of age.value, etc, it breaks.
I want to pass dynamic array values to java script function.how its possible.

I want to build a dynamic list of items with jquery but am unsure how to add an index number to each of the items i create so that i can reference them to edit or delete them for example. So far, I have the following which just creates the items and appends or prepends them to the element depending on whether one item exists already. I just need a way of adding an attribute so I can then reference the current item when clicked and remove it. What would be the simplest method to use?
//create list items
if ($('.mylistitem').length) {
$('.myList-box').prepend('<div class="mylistitem"><div class="mylistitem-image"><img width="30" height="40" src="[URL]"/></div><div class="mylistitem-title">' + title + '</div><div class="mylistitem-options"><a href="javascript:removetitle();">Delete From List</a></div>');
} else {
$('.myList-box').append('<div class="mylistitem"><div class="mylistitem-image"><img width="30" height="40" src="[URL]' + titleid + '"/></div><div class="mylistitem-title">' + title + '</div><div class="mylistitem-options"><a href="javascript:removetitle();">Delete From List</a></div>');
}
I'm creating a combobox using the Javascript and the DOM.
If the combobox exists, i don't want to create another one. I want to empty all the values and put new values.
I was able to create the combox and create the lines of code that deletes the values in the combobox (well almost) .....
i'm adding items to a select list like this:
var insertPoint = inst.getElementsByTagName("itemlist").item(0);
var itemCount = insertPoint.getElementsByTagName("item").length;
for(x=0;x<found.length;x++)
{
alert(found[x])
var item = document.createElementNS("", "item")
item.appendChild(document.createTextNode(found[x]))
insertPoint.appendChild(item)
}
Now if i want to delete all items of this select list how to do it?
I would like to know how to add/remove items from listbox PERMANENTLY. Sad to say, all I have found are adding/removing items temporarily.

I am having difficulties to deal with a simple remove function.
I have an item list with "listitem" css class. I placed a button on each item to delete it. I am now trying to use the remove function to erase it from the page. I thought $(this).remove(); will work but it doesn't. I also tried something like this: $(this).parent('.listitem').remove(); but it didn't work.
When I write $('.listitem').remove(); it erased all the items of the list. I m just trying to be able to erase just the one clicked.
Given the following HTML:
<ul>
<li class="">1</li>
<li>2</li>
<li>3</li>
[Code].....
Unfortunately that doesn't work. I understand that the index() isdocumentation (though confusing) correctly tells you that the above code doesn't work. Maybe I'm just weird, but I feel that the way .index() is implemented for string arguments is very counter intuitive. I have an expectation that .index() is similar to indexOf() in javascript.
I am fetching dataitems(store1) from the json file using IteamFileWriteStore and IteamFileReadStore and storing these items in the EnhancedGrid G1.
<table dojoType="dojox.grid.EnhancedGrid" jsid="grid2" id="grid2" store="store2"
plugins="{indirectSelection: true, selectable: true, dnd: true, nestedSorting: true,
loadingMessage: 'Loading...', errorMessage: 'An error exists within the data.' }"
selectionMode="extended" class="mainDojoTable float-left" style="width:180px;
height:300px;">

After Fetching the data from the grid1 of store1. Now, I need to Remove the Selected items in the grid2 to the grid1. After Removing the Selected items to the grid2 that items should be Added from the grid1.
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.
Code: function initArray() {
this.length = initArray.arguments.length;
for (var i = 0; i < this.length; i++) {[code].....
For the above piece of code, does the function 'function initArray()' just predefine the array that is written right after so that it's first array index starts at 1 instead of 0?
I have an array in which each element is a long string of various values separated by a particular character.I want to be able to search the array using the first value of each element to get the index.I cannot see how to do this so I have started to create a function for this.I want to take the original array, split out the value into another array and search the new array.I can then use the index returned to retrieve the full string from the original array.However I am having a problem when trying to set the new array and I do not know enough JS to understand what is going wrong.Here is the code:
Code:
<script type="text/javascript">
var test= new array();[code].......
I am getting the correct result in "title".I have tried setting "test[0]=title;" with an if on the first pass and then using ".push" but to no good effect.if there is a better way to achieve my objective or is this a reasonable solution

I have an array "arr" that is an array of objects. Each object has the same 7 properties.I want to find the index of the object with a property that matches a certain value x in the array arr. The array has hash tables associated with it.
arr [ obj [ i ] . property1 + "_" + obj [ i ] . property2 ] = arr [ i ] ;
so whats the index of the object where .property1 = x ?
