javascript - "Foreach" loop throw an error -
It looks simple, but I do not understand. So I have HTML
div class = "ui three column grid" data-bound = "foreach: stories" & gt; & Lt; Div class = "column" & gt; & Lt; Div class = "ui stacked segment" & gt; & Lt; Div class = "ui three column grid center align" & gt; & Lt; Div class = "column" & gt; & Lt; Div class = "ui button icon" & gt; & Lt; Div class = "UI button short" & gt; & Lt; I class = "icon plus" & gt; & Lt; / I & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div class = "column" & gt; & Lt; Div class = "ui label circular" & gt; & Lt; Div class = "ui label" & gt; 124124 & lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div class = "column" & gt; & Lt; Div class = "ui button icon" & gt; & Lt; Div class = "UI button short" & gt; & Lt; I class = "sign zero" & gt; & Lt; / I & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div class = "ui grid center align" & gt; & Lt; Div class = "row" & gt; & Lt; Div class = "column" & gt; & Lt; H1 & gt; Yo & lt; / H1> & Lt; / Div & gt; & Lt; / Div & gt; & Lt; Div class = "row" & gt; & Lt; Div class = "column" & gt; & Lt; Div class = "ui section" data-bind = "foreach: {data: stories.strings, like: 'string'}" & gt; & Lt; P data-bound = "text: string" & gt; & Lt; / P & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; & Lt; / Div & gt; Define my JS file with
(['knockout', 'datacontact'], function (to, datacontext) {viewModel = Activate: Main: Ko.SourceWeb (Stories), stories: K. OswevableAurre ([]),} Return ViewModel; Activate Function () {Return DataContacts.Gate Stories (.) Then (Function (data) {Console.log (Data.results); _.each (data. Result, function (result) {console.log (results.strings); Themodel.story.pash ({strings: results .string});}); console.log (viewModel .stories ());});}}) then foreach: Stories' is not working, that's the problem. The console shows me that "unable to binding process" foreach: function () {return stories} "message: unable to binding process": foreach: function () {return: {stories: stringings such as: 'string'} } "Message: stories are not defined;"
Exception is being thrown out due to its second foreach Is: & lt; Div class = "ui segment" data-bind = "foreach: {data: stories.strings, as: 'string'}" & gt; & Lt; P data-bound = "text: string" & gt; & Lt; / P & gt; & Lt; / Div & gt; Because you are in the context of writing "stories", throws stories.strings because there is no stories property Stories items so that you just have to type the string

Pass DB Connection parameters to a Kettle a.k.a PDI table Input step dynamically from Excel -
I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. 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
multithreading - PhantomJS-Node in a for Loop -
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] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
