elements

I want to get all innerText of a whole column of a very long html table (random length). I'm using this code: var tbEls = document.querySelectorAll('#tBodyID tr td:nth-child(cidx)'); Where cidx = the column index I want to extract content from. But such code extracts all the td elements (with the innerText inside them of course). But it doesn't extract directly all the innerText inside them. Cause of this I have to reprocess the returned tdEls array with a for loop to extract from each tbEls[i] element its own innerText. It works but... My question is: In pure JS (no external libraries or

I am trying to edit an XML file with Wix. I am using the WixUtilExtension bundled with Wix 3.7. The xml file is a settings file created in Visual Studio 2010 for a C# application. In this file, I am using an element which is used to store multiple string values in an array. This is the content of the unaltered settings file: <configuration> <applicationSettings> <AppName.Properties.Settings> <setting name="StringArray" serializeAs="Xml"> <value> <ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> </ArrayOfString> </value> </setting

下面我们用两种方法实现冒泡排序： var afterDelete = [11, 2, 6, 31, 5] 方法一： function range(arr) { for(var i=0;i<arr.length-1;i++){ //索引值是i的数字和排在它后面的所有数字依次比较一次 for (var j = i + 1;j < arr.length;j++){ if (arr[i] > arr[j]) { var temp = arr[j]; arr[j] = arr[i]; arr[i] = temp; } } } return arr } var rangeResult = range(afterDelete) console.log(rangeResult) // [2, 5, 6, 11, 31] 方法二： function quickSort(elements){ if(elements.length<=1){ return elements; } var index = Math.floor(elements.length/2); //console.log(index);//5->5->4->3->2->2->1 var pivot = elements.splice(index,1)[0];//获取删除的数字 //console.log("pivot="+pivot)

How can I generate unique sets of 5 numbers of every possible combination from 1 to 56, using an SQL statement? In APL (programming language) a simple dyadic function 5!56 does the trick!
