I am trying to code the equivalent to the EXCEL PMT function. in Java Script, the formula looks like this: function PMT (ir, np, pv, fv ) { /* ir - interest rate per month np - number of periods (months) pv - present value fv - future value (residual value) */ pmt = ( ir * ( pv * Math.pow ( (ir+1), np ) + fv ) ) / ( ( ir + 1 ) * ( Math.pow ( (ir+1), np) -1 ) ); return pmt; } This is great for PMT calcs where Type =1 (i.e. payments occur at the start of the period) However, I'm trying to code for a Type 0 scenario (i.e. payments occur at the end of the period)). Any math wizards out there who

I want to get unique values from two different arrays. Two arrays are as below in JavaScript: <script> var a=new Array; var b=new Array; a={'a','b','c','d','e'} b={'a','d','e','c'} </script> I want output like: new array => {'a','c','d','e'} How can I find unique records from both arrays using JavaScript prototype function or jQuery function? I don't know if you have the terms correct. Unique values to me would be members which appear only once in either array. It seems you want members that are present in both arrays (common values, or intersection ), based on your example. You can use jQuery

I am trying to use a function in a controller to return data so that I can re-use the function across the app to call the data as well as refresh it occasionally. My code appears correct, but in practice, crashes the browser on each load. I am able to get it to work by using an E directive and then placing the element in the partial, but that doesn't accomplish what I need. Ultimately, I would like to do something like this: <div ng-repeat="user in getListUsers()">{{ user.somedata }}</div> I have tried various things to get it to work in testing, including putting the $http in the controller,

Does anyone know the jQuery equivalent for window.document.write('') in javascript? Thanks This will add the string "hello" right before the body closing tag. Not exactly the behavior of write , but you can do this to any element to get the content to appear where you want it. $(document.body).append('hello'); Also available are prepend(content) and replaceWith(content) for all your insertion needs! First, jQuery is JavaScript, it is just a library of functions to make coding easier. Second, you should avoid the use of document.write . You should use jQuery to append the text to the DOM

I'm using jointjs to make diagrams which will be user-editable. The user may drag them around and relocate each cell. However, when a cell is dragged to the edge, it overflows and becomes cut off. I want to prevent this from happening, instead the cell to stop before it gets to the edge of the paper and not be allowed to cross the edge, thus always staying completely within the paper. The behavior can be seen in jointjs' very own demos here: http://www.jointjs.com/tutorial/ports Try dragging the cell to the edge and you'll see that it eventually becomes hidden as it crosses the edge of the
