angularjs - Adding extra elements conditionally with ng-repeat -

-

I am using bootstrap and want to create lines of content with each row of three rows, where each column Content will be represented in NG-Dual in an object

It will look like this: 

  & lt; Div class = "row" & gt; & Lt; Div class = "col-md-4" & gt; & Lt; div class = "panel panel-primary" & gt; & Lt; div class = "panel-title" & gt; & Lt; H3 class = "panel-title" & gt; Panel title & lt; / H3 & gt; & Lt; / Div & gt; & Lt; Div class = "panel-body" & gt; Panel content & lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div class = "col-md-4" & gt; & Lt; div class = "panel panel-primary" & gt; & Lt; div class = "panel-title" & gt; & Lt; H3 class = "panel-title" & gt; Panel title & lt; / H3 & gt; & Lt; / Div & gt; & Lt; Div class = "panel-body" & gt; Panel content & lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div class = "col-md-4" & gt; & Lt; div class = "panel panel-primary" & gt; & Lt; div class = "panel-title" & gt; & Lt; H3 class = "panel-title" & gt; Panel title & lt; / H3 & gt; & Lt; / Div & gt; & Lt; Div class = "panel-body" & gt; Panel content & lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div class = "row" & gt; & Lt; Div class = "col-md-4" & gt; & Lt; div class = "panel panel-primary" & gt; & Lt; div class = "panel-title" & gt; & Lt; H3 class = "panel-title" & gt; Panel title & lt; / H3 & gt; & Lt; / Div & gt; & Lt; Div class = "panel-body" & gt; Panel content & lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div class = "col-md-4" & gt; & Lt; div class = "panel panel-primary" & gt; & Lt; div class = "panel-title" & gt; & Lt; H3 class = "panel-title" & gt; Panel title & lt; / H3 & gt; & Lt; / Div & gt; & Lt; Div class = "panel-body" & gt; Panel content & lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div class = "col-md-4" & gt; & Lt; div class = "panel panel-primary" & gt; & Lt; div class = "panel-title" & gt; & Lt; H3 class = "panel-title" & gt; Panel title & lt; / H3 & gt; & Lt; / Div & gt; & Lt; Div class = "panel-body" & gt; Panel content & lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt;   
 What is the best way to go about this? I must  
  & lt; / Div & gt; Need to add something along the lines of I & Lt; Div class = "row" & gt;   
 Between every three items in NG-repeat.   
 
 
 I'm sure you want to display 3 panels per line  
 If you are using  col-md-4  on your panel, then Bootstrap will hold 3 panels on each line (as long as the screen size is at least MD size) - Therefore, each three rows Adding  line  to is not unnecessary, it can also prevent some functionalists (such as for SD devices) A. Display only 2).  
 In relation to angular, you can use the index inside the loop using the  $ index .

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go.

Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
