LINQ In Javascript

By the following code you can use the LINQ in javascript.

For that you need JSLINQ.js file.

You will get it from http://jslinq.codeplex.com/releases/view/28886

<script type=”text/javascript” src=”JSLINQ.js”></script>
<script type=”text/javascript”>
function LINQInJavaScript() {
var myList = [
{ FirstName: “Chris”, LastName: “Pearson” },
{ FirstName: “Kate”, LastName: “Johnson” },
{ FirstName: “Josh”, LastName: “Sutherland” },
{ FirstName: “John”, LastName: “Ronald” },
{ FirstName: “Steve”, LastName: “Pinkerton” }
];
var whereExample1 = JSLINQ(myList).Where(function(item) { return item.FirstName == “Chris”; });
alert(whereExample1.items[0].FirstName);
</script>

 

 

Javascript function for multiplication in table dynamically

Consider the table will be generated dynamically like below,

For ex,

var table = document.getElementById(“DynamicTable”);//In this div, you have to put table tag.
for (var i = 0; i <= rowLength; i++) {
var row = table.insertRow(i);
for (var j = 0; j < columnLength + extraColumns; j++) {
var col = row.insertCell(j);
col.innerHTML = “<input type=’text’ onkeyup=’GetSelectedRow(this)’/>’;
}
}

Then function will be follows,

function GetSelectedRow(txt) {
var row = txt.parentNode.parentNode;
var price = Number(row.cells[0].getElementsByTagName(“input”)[0].value);
var qty = Number(row.cells[1].getElementsByTagName(“input”)[0].value);
var Total = price * qty;
row.cells[2].innerHTML = Total;
}
