I've set the following comparator on columnDef
...
comparator: (date1: string, date2: string): number => this.dateComparator(date1,date2),
...
and have a custom function to sort strings as dates as below
dateComparator(date1: string, date2: string): number {
const d1 = new Date(date1);
const d2 = new Date(date2);
//custom logic and return..
}
However, the date1 and date2 parameters are undefined. can someone help with this please.
I have written the same comparator
export function dateComparator(date1: string, date2: string) {
const date1Number = date1 ? new Date(date1).getTime() : null;
const date2Number = date2 ? new Date(date2).getTime() : null;
if (date1Number === null && date2Number === null) {
return 0;
}
if (date1Number === null) {
return -1;
}
if (date2Number === null) {
return 1;
}
return date1Number - date2Number;
}
But if you change your value of the cell in some cases (from date to string - like in my case if date is null I am showinng 'Never Logged' then we should replace it) - and showing just a string you can use the next comparator:
export function dateComparator(date1: string, date2: string) {
const neverLog = 'Never Logged';
const date1Number = date1 === neverLog ? null : new Date(date1).getTime();
const date2Number = date2 === neverLog ? null : new Date(date2).getTime();
if (date1Number === null && date2Number === null) {
return 0;
}
if (date1Number === null) {
return -1;
}
if (date2Number === null) {
return 1;
}
return date1Number - date2Number; }
if you are not sure whether the date value which is being passed in the comparator is valid string or not then you can check it first and sanitize it before comparing.
function dateComparator(date1, date2) {
var date1Number = validateDateinput(date1);
var date2Number = validateDateinput(date2);
if (date1Number === null && date2Number === null) {
return 0;
}
if (date1Number === null) {
return -1;
}
if (date2Number === null) {
return 1;
}
//custom logic and return..
return date1Number - date2Number;
}
function validateDateinput(date) {
// handle null and undefined values. add more logic here as per use case
if (date === undefined || date === null) {
return null;
}
//string is valid to create date
return new Date(date);
}
I want,
If B1 edited/Not empty, put TimeStamp on A1. here is my script-
function onEdit() {
var s = SpreadsheetApp.getActiveSheet();
if( s.getName() == "Sheet1" ) { //checks that we're on the correct sheet
var r = s.getActiveCell();
if( r.getColumn() == 2 ) { //checks the column
var nextCell = s.getRange(r, 1);
if( nextCell.getValue() !== '' ) //is not empty
nextCell.setValue(new Date());
}
}
}
Problem is, getRange(r, 1) which should be getRange(r, -1) as colB=0, colC=1 colA=-1
But putting -1 is not working. How to fix that??
try this...
if(r.getColumn() == 2){
var prevCellValue = r.offset(0,-1).getValue;
if(prevCellValue() !== ''){
r.offset(0,-1).setValue(new Date());
}
}
I trying to update code from extjs2 to extjs4. But I have a some problem with load event in Ext.data.DataProxy.
Ext.define('App.data.DwrProxy', {
extend: 'Ext.data.DataProxy',
constructor: function(config){
App.data.DwrProxy.superclass.constructor.call(this);
this.invoker = config.invoker;
},
load: function(params, reader, callback, scope, arg) {
if (this.fireEvent("beforeload", this, params) !== false) {
if (!this.invoker) {
alert("'invoker' property is not specified");
return;
}
this.reader = reader;
this.callback = callback;
this.scope = scope;
this.arg = arg;
params.gridState = params.gridState || {};
if (params.sort != null)
params.gridState.sortField = params.sort;
if (params.dir == 'ASC')
params.gridState.descendingOrder = false;
if (params.dir == 'DESC')
params.gridState.descendingOrder = true;
if (params.start != null) {
params.gridState.pageNo = Math.floor(params.start / params.limit);
if (isNaN(params.gridState.pageNo))
params.gridState.pageNo = 0;
}
if (params.limit != null)
params.gridState.pageSize = params.limit;
this.invoker.call(
scope || this,
params,
arg,
{
callback: Ext.bind(this.success, this),
errorHandler: Ext.bind(this.failure, this)
}
);
} else {
callback.call(scope || this, null, arg, false);
}
}
});
As I know, Ext.data.DataProxy load event don't support in extjs4. So, how to use this function?
I used read instead and it worked for me.
I have asked a question like this before, and the answer was great but the more I looked at my code the more confused I got, and after 10hrs my brain is shot and I'm in need of help. So all my content is loaded dynamically via Jquery's $.post and loaded into #content-container. Now I included my entire Jquery file to show you why I am getting so confused as how to get this to work without re-writing all the code. As you can see, and what I'm thinking, is that the history plugins such as BBQ, and history.js seem to be out of the question because I don't use anchor tags and the multitude of .live('click', funcition() { I have use different classes and id's for various reasons. I also believe that rules out using the hash and linking it to a single class via .trigger(), executing the AJAX(hope that makes sense). The only option I have left is actually kinda my question. Would it be possible to load the dynamic content into #content-container still using the $.post with $.load() or window.location and actually have the previous content loaded when the browser back button is clicked.
I greatly appreciate the help, really.....
