Now, if I want to get all the list items after the first, and change the text within the anchor tags, if a certain condition is met (eg change to capitals if it starts with a "t"). How can I do that? My approach was to get all the list items (after the first) with
I am trying some simple things with javascript and trying to use it in a object oriented way. However I am now facing a problem in which I can't access an object variable from an object method. I am using jQuery.
My code is as follows;
Code:
My problem is that the variable msg1 does not work when accessed from function called from the jQuery get function. I get the message undefined. Therefore I am wondering, is there a way how I can access msg1 of my object instance from the get function of jQuery?
Now we have alerts only for three old elements. This is clear. Because these elementes have been initiated before page generated. But the new one is ignored.
The question is - how i can add new elements to the UL list? It would be glad if "jQuery.each" could read four and more elements - not just the first three initiated elements.
I've created an object with properties and methods. The object is associated with a form. The object iterates through the form and finds any inputs that are required. It then uses each to apply validation to each of the found inputs. From within each(), I need to access properties and methods of the parent object, but now this refers to the current collection object. How do I access the containing object?
If "this" inside of a sortable "receive" function refers to the receiving object, How do I access the object to which the receive function belongs?
Example: // Function that takes a JQ object and makes it sortable. // We assign the "SortableRecieve" method to the receive event MyObject.prototype.MakeSortable = function(JQOBJ){ JQOBJ.sortable({ receive: this.SortableRecieve });}
MyObject.prototype.DoSomething = function(){ // Does something important } // The actual function that gets called when the receive event occurs MyObject.prototype.SortableRecieve = function(event, ui){ // This function call won't work, because "this" // doesn't point to the right thing! this.DoSomething(); } So how can I access the "True" this that refers to the object?
I am trying to access my own JS object from within an ajax call, and can't figure out how to get it to work Whenever I access "this" in the function, it returns the ajax context and not my JS object context. My code looks something like this. I have a Zone object defined in a JS file like this:
how can I detect if mouse cursor is over or out of some element? I am running a animation, which I don't want to run or to stop itself if cursor gets to area.
I have a table that has four columns in it. The second to last column has checkboxes in it. The last column has pulldowns in it with the class of "change_order". How can I make changes to the adjacent pulldown when the checkbox (in same row) is checked/unchecked? I am not able to select it.
function updateOrder(obj){ $j(obj).nextAll(".change_order").addClass("changedPD"); }
The code : $('.TextHover').editable('/Task/SaveTags.php', { type : 'text', cancel : 'Cancel', submit : 'Ok',

I put on alert to help me debug the returned value.What I need to show on alert is the 3, text of td with id='tId'.$(this).closest('tr').closest('td#tId').text() wouldn't work.$(this).closest('tr').next('td').html() returns null.
I have 95 different objects like this one: obj1Object = { name: "some name", type: "type", picid: "001", maxvl: 500000, minvl: 5000, clsid: 1, movable: true, size: [45, 45], note: "Some text here" } Now what I need is to access these objects only when I need then. Right now they all load when accessing my program so all 95 of them are "somewhere" in memory.
I want to start traversing backwards from the previous sibling of a specific div element. I've tried something like this but it does not seem to work because it's only selecting the specific div:
var start = $("#specific_div").prev("div"); // start from the previous div sibling of the "specific div"
I have a javascript object which dynamically generates a table adding, deleting and moving rows as the user clicks on buttons or links. Problem is when I generate a table row and add the javascript method call to my class, I have to put the object instance name variable of the class in order for it to be called from the onclick=function(). This is seriously limiting, but I'm stuck for a way round it. Heres a edited of the code so you get the idea....
Instantiating the object :-
var dtl = new DynamicTableList("table1", $ {myObject.allFieldsAsJavaScriptArray}, true, true, true);
My javascript class DynamicTableList, note the dtl javascript object instance variable being referred to in the addRow function. How can I avoid this???
if (showDelete) { var cell2 = document.createElement('TD'); var inp2 = document.createElement('IMG'); / ************************************************** ***********************************************/ inp2.onclick=function(){dtl.delRow(this);} // Have to specify dtc!!!!!!!! / ************************************************** ***********************************************/ inp2.title='Delete' inp2.alt='Delete' inp2.src='images/delete.gif' cell2.appendChild(inp2); row.appendChild(cell2); }
...
tbody.appendChild(row);
this.processRows(); };
this.moveRow = function(node, vector) { }; }
Obviously the code dtl.delRow(this); is being dynamically generated, but how do I replace the dtl instance name with something that'll work whatever the user of this class calls the instance of it!
I am fairly familiar with the concept of Objects and their properties and methods, but javascript being object based as opposed to object oriented has me stumped on how to access an object's properties from an onclick event handler created for another object created within the original object.
In the example below, I have a constructor function called anyObj. to which I pass an object reference to an element.
anyObj has 3 properties and one function increaseWidth()
increaseWidth() creates a new button with an onclick event handler and this is where I have a problem.
The onclick function needs to increase the value of anyObj's this.width property. I originally had a line this.width += 10; in the onclick but quickly realised why this wasn't working because the this in the onclick function refers to the new button object and not the this.width property of anyObj.
The workaround I have used, and it works, is to make a copy of all the this.xxxxx properties. eg. width = this.width; and use the width variable in the onclick as you can see below. This "workaround" works fine but doesn't feel ideal to me.
So is there a better way to access the anyObj()'s properties from within the onclick function than the way I have done it? Obviously I would prefer to not have to make copies of all the anyObj() properties like I have to make them accessible to the onclick function.
I have a JS method register in a TD element as below:
Below is the Js Method:
The JS method works fine in IE but in mozilla throws an error that event is undefined.
I cant pass the event object from HTML while registering the method as HTML is written by someone else and I cannot change that. All I can change is the JS method.
I've created an object and within this object, I've added an eventlistener. But the problem now is that after addEventListener is being called to access a callback function, the callback function is not able to access the properties within its own class. Code:
I need to acsess an object property via variables, but don't get ahead.
Example:
var property = height;
"height" is a property of the object "flower". Now, I need a possibility to access "flower.height" with my variable property, means -->"flower.property" I tried everything like "flower.[property]" "flower.['property']" etc. but nothing did help.
Am passing an array object back from ASP.NET but cannot work out how to access the child objects and get the value. Link is an image of the asp return object and what I am able view in javascript by console log of the data. Example image - [URL] been trying stuff like data.d.MessageText and a few others.
I have a form that submits to a third party WCF service. When the form submits it returns html. Based on that html I need my ajax submit to fire a success function according to the reply. The reply is as such: <HTML><BODY> <TABLE border='1'> <TR><TD><b>Field Name</b></TD> <TD><b>Field Value</b></TD> </TR><TR> <TD>SuccessFlag</TD> <TD>TRUE</TD> </TR><TR> <TD>ResponseMessage</TD> <TD>Service Cancelled</TD> </TR></TABLE></BODY></HTML>
How would I write a success function if the SuccessFlag returns a TRUE in that td? I have tried success: function(data) { var useTD = $(data).find('table').children('tbody tr td:nth(4)'); if (useTD == 1) { $("#request").remove(); $("#requestSuccess").fadeIn("slow"); } else { $("#request").remove(); $("#requestError").fadeIn("slow"); } To no avail. I have also tried using the :contains but I can't get that right either.
