http://aspsolution.net/Code/5/5215/How-to-loop-through-ViewBag-List-in-Jquery/#
I followed what is written in the website. However the Json.Result doesn't appear. I tried to include this one (#using Newtonsoft.Json) in the html but it's still not appearing. Why is that? Is there any solution for this?
This is my script:
fillDatatable();
function fillDatatable() {
var cart = #Html.Raw(Json.Result(#ViewBag.cart));
alert(cart.Items.ItemID);
}
Edited:
if (PurchaseOrder != "") {
var tableHTML = '';
$.each(PurchaseOrder, function (index, value) {
tableHTML += "<tr>";
tableHTML += "<td>" + value.items.itemID + "</td>";
tableHTML += "<td>" + value.items.itemModelDescription + "</td>";
tableHTML += "<td>";
tableHTML += "<input id='UnitPrice" + value.items.ItemID + "' class='form-control b-r-xl text-right' value='" + value.items.itemUnitPrice + "' oninput='return change_unitprice('" + value.items.itemID + "')' />";
tableHTML += "</td>";
tableHTML += "<td>";
tableHTML += " </tr>";
});
$("#TableRecords").html(tableHTML);
}
See my HTML inside the loop where you can see change_unitprice function. I'm trying to pass the value of an id there, but according to the result of console it is undefined? Why is that?
The example you are referencing does not contain the code you included to the question. It describes how to use Json.Encode() to obtain data from the ViewBag field. Possible problems why your code doesn't work are:
Using not defined the cart field.
Using the Items property that does not defined.
Trying to work with HTML document that does not loaded yet.
Therefore, use function from this example as is:
<script>
$(document).ready(function(){
var StockList =#Html.Raw(Json.Encode(#ViewBag.StockList));
if (StockList != '') {
var tableHtml;
$.each(StockList, function( index, value ) {
tableHtml +="<tr><td>" + value.stockId + "</td><td>" + value.StockName + "</td><td>" + value.StockPrice + "</td></tr>";
});
$("#output").html(tableHtml);
}
})
</script>
If it does not work (probably because of the jquery disable by Layout = null; line in the Index.cshtml ) add the following line after the <head> tag:
<script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery/jquery-1.6.2.min.js"></script>
For additional information see the following post: https://stackoverflow.com/a/10779161/6630084
I think the simplest method that works for complex object would be like this:
#Html.Raw(Json.Encode(ViewBag.cart))
How can I get the name and model of the system processor CPU in the inject content script?
Is there a way to access chrome.system.cpu in inject content script?
I saw this code from David Christian who wrote in the popup.js file that it works but I do not know how I can access its function in the inject content script.
Please help me.
// David Christian
// System info Chrome extension
var systemInformation = {
requestInfo: function() {
chrome.system.cpu.getInfo(function (cpuInfo){
var elem = document.getElementById('cpu');
var info = cpuInfo.modelName + "<br>";
info += "Architecture: " + cpuInfo.archName + "<br>";
info += "Cores: " + cpuInfo.numOfProcessors.toString() + "<br>";
// info += "Features: " + cpuInfo.features + "<br>";
info += "<table><tr><th>#</th><th>User (ms)</th><th>Kernel (ms)</th><th>Idle (ms)</th><th>Total (ms)</th></tr>";
for (var i=0; i < cpuInfo.processors.length; i++){
info += "<tr><td>" + i + "</td>";
info += "<td>" + cpuInfo.processors[i].usage.user + "</td>";
info += "<td>" + cpuInfo.processors[i].usage.kernel + "</td>";
info += "<td>" + cpuInfo.processors[i].usage.idle + "</td>";
info += "<td>" + cpuInfo.processors[i].usage.total + "</td><tr>";
}
elem.innerHTML = info + "</table>";
});
chrome.system.memory.getInfo(function (ramInfo){
var elem = document.getElementById('ram');
elem.innerHTML = (ramInfo.availableCapacity / 1073741824).toFixed(2)
+ "gb / " + Math.round(ramInfo.capacity / 1073741824).toFixed(2)
+ "gb (" + ((ramInfo.availableCapacity / ramInfo.capacity) * 100.0).toFixed(2).toString() + "% available)";
});
}
};
// Start getting system data as soon as page is ready..
document.addEventListener('DOMContentLoaded', function () {
// Ensure that we have a display straight away
systemInformation.requestInfo();
// Update the display every 3 seconds
setInterval(systemInformation.requestInfo, 3000);
});
Here is my JSON
var gal = [
{
"folder":"nu_images",
"pic":"gd_42.jpg",
"boxclass":"pirobox_gall",
"alt":"Rand Poster 1",
"title":"Rand Poster 1",
"thfolder":"th",
"thumbpic":"th_gd_42.jpg"
},
{
"folder":"nu_images",
"pic":"gd_13.jpg",
"boxclass":"pirobox_gall",
"alt":"Explosive Pixel Design",
"title":"Explosive Pixel Design",
"thfolder":"th",
"thumbpic":"th_gd_13.jpg"
}
];
and here is my for loop
for (i = 0; i < gal.length; i++) {
document.getElementById("gallery").innerHTML = "" + "<img src=\"" + "http:\/\/galnova.com\/" + gal[i].folder + "\/" + "th\/" + gal[i].thumbpic + "\"" + "border=\"0\"" + "alt=\"" + gal[i].alt + "\"" + "title=\"" + gal[i].title + "\"\/>" + ""
};
I am trying to make my JSON show all of the objects in HTML one after the other. I can get it to show the first one or whatever number I put into the array but I don't know how to make it generate a list of them.
Here is a link to my jsfiddle. Any help you can offer would be greatly appreciated.

It's being generated here <p id="gallery"></p> just not correctly.
You're overwriting your html with every loop iteration:
document.getElementById("gallery").innerHTML = ...
^---
Perhaps you want something more like
document.getElementById("gallery").innerHTML += ...
^---
which will concatenation the original html contents with your new stuff.
And technically, you shouldn't be doing this in a loop. Changing .innerHTML like that causes the document to be reflowed/re-rendered each time you change .innerHTML, which gets very expensive when you do it in a loop. You should be building your html as a plain string, THEN adding it to the dom.
e.g.
var str = '';
foreach(...) {
str += 'new html here';
}
document.getElementById("gallery").innerHTML += str;
for (i = 0; i < gal.length; i++) {
document.getElementById("gallery").innerHTML += "" + "<img src=\"" + "http:\/\/galnova.com\/" + gal[i].folder + "\/" + "th\/" + gal[i].thumbpic + "\"" + "border=\"0\"" + "alt=\"" + gal[i].alt + "\"" + "title=\"" + gal[i].title + "\"\/>" + "" };
Add a += instead of an = after innerHTML
Try this:
function displayJson(jsonArray){
var container = document.getElementById("gallery");
for (var i=0; i<jsonArray.length; i++){
var newElement = document.createElement("a").innerHTML = jsonToHtml(jsonArray[i])
container.appendChild(newElement);
}
}
function jsonToHtml(jsonObj){
//Define your dom object here
var el = document.createElement("a").innerHTML = '' // you code here
...
return el;
}
displayJson(gal);
hello i need a 3 colums layout in jquery mobile.
i load my json file and i need to put the first obj in ui-block-a the second obj in ui-block-b the third obj in ui-block-c the fourth obj in ui-block-a and so on....
i can make with two colums checking if is odd or even, this is my code:
for (var i in data.cappelli) {
if( i%2 == 0)output+="<div class=\"ui-block-a\">" + data.cappelli[i].id + " " + data.cappelli[i].nome + "</div>";
else output+="<div class=\"ui-block-b\">" + data.cappelli[i].id + " " + data.cappelli[i].nome + "</div>";
}
can someone help me to achieve that in 3 column??
Ty very much
grids = ['a','b','c'];
for (var i in data.cappelli) {
output+="<div class=\"ui-block-" + grids[i%3] + "\">" + data.cappelli[i].id + " " + data.cappelli[i].nome + "</div>";
}
I've been working with highcharts and MVC 3 for two years by now (I never done anything complicated, just load data and make it work stuff), and I worked with two different scenarios:
Chart code written in the directly in the view, loading data through Json
Html helper responsible to plot the chart
The Html helper approach seems to me a more elegant choice ... but then, just to illustrate to you guys, here is how it looks like (just part of it):
public static string DisplayChart(
this HtmlHelper helper,
ChartOptions options,
TimedChartSeries[] data)
{
string[] axisList = data.GroupBy(t => t.Unit).Select(t => t.Key).ToArray();
string result = "";
result += "<script type=\"text/javascript\">\n";
result += "var " + options.ChartName + ";\n";
result += "$(document).ready(function() {\n";
result += options.ChartName + "= new Highcharts.Chart({\n";
result += "chart: {renderTo: '" + options.DivName + "',zoomType: ''},\n";
result += "title: { text: '" + options.Title + "'},\n";
result += "subtitle: {text: '" + options.SubTitle + "'},\n";
result += "xAxis: { type: 'datetime'," +
"\n dateTimeLabelFormats: {month: '%e. %b', year: '%b' },"
+ "labels:{rotation: -45}\n},\n";
string axes = "";
for (int i = 0; i < axisList.Length; i++)
{
var temporaryData = data.First(t => t.Unit == axisList[i]);
if (i != 0)
axes += ", ";
axes += "{labels:{\n " +
"formatter : function(){return this.value + '" + temporaryData.Unit + "';},\n" +
"style:{color:'#" + temporaryData.Color.Name.Remove(0, 2) + "'}},\n" +
"title:{text:'',style:{color:'#" + temporaryData.Color.Name.Remove(0, 2) + "'}},\n" +
"}\n";
}
result += "yAxis: [\n" + axes + "],\n";
string units = "";
for (int i = 0; i < data.Length; i++)
{
if (i != 0)
units += ", ";
units += "'" + data[i].Title + "': '" + data[i].Unit + "'\n";
}
result += "tooltip:{\nshared: true,\n backgroundColor: 'none' ,\nborderColor: 'none'," +
"\nshadow:false\n ,crosshairs: true,\n" +
"formatter: function() {var s = '<table class=\"table-list\"><tr><th>Hora</th><th>'+ test(this.x) +'</th></tr>';" +
"\n$.each(this.points, function(i, point) {" +
"\ns += '<tr><td>'+point.series.name + '</td><td>'+point.y+'</td></tr>'});s+='</table>';" +
"\n$('#tooltip').html(s);}},";
result += "lang: {" +
"months: ['Janeiro', 'Fevereiro', 'Março', 'Abril', 'Maio', 'Junho'," +
"'Julho', 'Agosto', 'Setembro', 'Outubro', 'Novembro', 'Dezembro']," +
"weekdays: ['Domingo', 'Segunda', 'Terça', 'Quarta', 'Quinta', 'Sexta', 'Sábado']},";
string series = "";
int x = 0;
for (int j = 0; j < axisList.Length; j++)
{
var temporaryData = data.Where(t => t.Unit == axisList[j]).ToArray();
for (int i = 0; i < temporaryData.Length; i++)
{
if (x > 0)
series += ", ";
series += "{name: '" + temporaryData[i].Title + "',\n color: '#" + temporaryData[i].Color.Name.Remove(0, 2) +
"', \ntype: '" + temporaryData[i].Type + "',\nunit:'" + temporaryData.First().Unit + "', \nyAxis:" + j + " , \ndata:[" + FromArrayToString(temporaryData[i].Data) +
"], marker: { enabled: false}}\n";
x++;
}
}
result += "series: [\n" + series + "]\n";
result += "});});";
result += "\nfunction test(i)\n{\nvar j = new Date(i + 2*60*60*1000);\n" +
"return new Date(i + 3*60*60*1000).format('d/m/Y H:i:s.')+j.getMilliseconds();\n}\n</script>";
result += "\n<div id=\"" + options.DivName + "\" style=\"width:" + options.Width + ";height: " + options.Height + "\"></div>" +
"<div id=\"tooltip\"></div>";
return result;
}
It's really simple to call this helper:
#Html.Raw(Html.DisplayChart((ChartOptions)Model.Options,(TimedChartSeries[])Model.Series))
As you guys can see, I have to use the Html.Raw helper in order to make it work ... that is problem nº 1 (and it probably has an easy solution). But the second problem is really great: the chart becomes entirely tied to my domain. If I wanted to plot a, say, bar chart displaying data of the last 3 years in months (each month being represented by a bar), it would be impossible to use this helper.
And it also looks kind of ugly.
So, guys, which option do you think is more elegant, the Json or the Helper approach?
About the use of Html.Raw and the easy solution:
Change your function to
public static HtmlString DisplayChart(this HtmlHelper helper, ...)
{
...
return new HtmlString(result);
}
You then may use #Html.DisplayChart(...) in your razor views.
Also, please make sure that options.DivName, options.Title, options.SubTitle etc. are properly escaped - a title like Everybody's favorite chart will break the output.
