javascript - D3 update data on the wrong bars -


i want update data on click bars changing not right ones. there cant quite fix select. on click grey bars, should bar2 updating. should bar.

example: https://jsfiddle.net/monduiz/kaqv37gu/

d3 chart:

var values = feature.properties; var data = [     {name:"employment rate",value:values["erate15p"]},     {name:"participation rate",value:values["pr15p"]},     {name:"unemployment rate",value:values["urate15p"]} ];  var margin = {top: 70, right: 50, bottom: 20, left: 50},     width = 400 - margin.left - margin.right,     height = 270 - margin.top - margin.bottom,     barheight = height / data.length;  // scale x axis var x = d3.scale.linear()     .domain([0, 100]) //set input scale of 0 - 1. index has score scale of 0 1. makes bars more accurate comparison.     .range([0, width]);  var y = d3.scale.ordinal()     .domain(["employment rate", "participation rate", "unemployment rate"])     .rangeroundbands([0, height], 0.2);  var svg = d3.select(div).select("svg")     .attr("width", width + margin.left + margin.right)     .attr("height", height + margin.top + margin.bottom)     .append("g")     .attr("transform", "translate(" + margin.left + "," + margin.top + ")")     .classed("chartind", true);  var bar2 = svg.selectall("g.bar")     .data(data)     .enter()     .append("g")     .attr("transform", function(d, i) { return "translate(0," + * barheight + ")"; });  var bar = svg.selectall("g.bar")     .data(data)     .enter()     .append("g")     .attr("transform", function(d, i) { return "translate(0," + * barheight + ")"; });   bar2.append("rect")     .attr("height", y.rangeband()-15)     .attr("fill", "#ededed")     .attr("width", 300);   bar.append("rect")     .attr("height", y.rangeband()-15)     .attr("fill", "#b44978")     .attr("width", function(d){return x(d.value);});  bar.append("text")     .attr("class", "text")     .attr("x", 298)     .attr("y", y.rangeband() - 50)     .text(function(d) { return d.value + " %"; })     .attr("fill", "black")     .attr("text-anchor", "end");  bar.append("text")     .attr("class", "text")     .attr("x", function(d) { return x(d.name) -5 ; })     .attr("y", y.rangeband()-50)     //.attr("dy", ".35em")     .text(function(d) { return d.name; });  d3.select("p")             .on("click", function() {                 //new values dataset                 var values = feature.properties;             var dataset = [                             {name:"employment rate",value:values["erate15_24"]},                             {name:"participation rate",value:values["pr15_24"]},                             {name:"unemployment rate",value:values["urate15_24"]}                           ];                 //update rects                 var bar = svg.selectall("rect")                    .data(dataset)                    .attr("x", function(d){return x(d.value);})                    .attr("width", function(d){return x(d.value);})                    });      } 

var bar2 = svg.selectall("g.bar")     .data(data)     .enter()     .append("g")     .attr("transform", function(d, i) { return "translate(0," + * barheight + ")"; });  var bar = svg.selectall("g.bar")     .data(data)     .enter()     .append("g")     .attr("transform", function(d, i) { return "translate(0," + * barheight + ")"; });

'bar2' above generates 3 new g elements (one each datum)

since don't set attr("class","bar") these 'bar' generate 3 new g elements - (if had set class attribute bar return empty no new elements generated , you'd see missing stuff)

further on add rects these g elements 6 rectangles in total , in click function select these rectangles , re-attach 3 fresh bits of data

since bar2 added first rectangles in g elements hoovering new data

you need select , set different classes on g elements, .selectall("g.bar") , .attr("class", "bar") bar, , .selectall("g.bar2") , .attr("class", "bar2") bar2 (use same name keep simple)

then in new data need select rects belonging g elements of bar class: svg.selectall(".bar rect")

another way have 1 set of g elements , add 2 types of rectangle (differentiated class attribute)

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...

ruby on rails - Seeing duplicate requests handled with Unicorn -

recently upgraded our ec2 instances c3.large in order boost more unicorn workers handle increased traffic our site. (6xworkers per machine - 2 ec2 instances). when did this, started seeing duplicate records being created! looks somehow, maybe 2 unicorn workers attempting process same request? in nginx logs see 1 [post] request particular rails controller - yet 2 records being created in database. i'm hitting kind of race condition issue - have no idea how debug this. doesn't happen time, when it's frustrating well. noticed 2 database records within 5 seconds of each other. (and yes disable button when user clicks submit button). unicorn 4.8.2 ruby 1.9.3 rails 3.2.14 any great! thanks! although may not fix problem, upgrade ruby 2.0.0. there blog mentioning idea upgrade ruby 2.0.0 if using unicorn. for example: https://www.digitalocean.com/community/articles/how-to-optimize-unicorn-workers-in-a-ruby-on-rails-app specifically: if using ruby 1.9, ...
