How to know row number when typing in input field in table



In my XML view, I have a Table, in that Table I have Input field at a particular column, and I have a function for liveChange event of that Input field. Code is like below:


<Table ...>
<columns> ... </columns>
<items>
<ColumnListItem>
<cells>
......
<Input type ="Number" value="..." liveChange="qtyChanged"/>
</cells>
</ColumnListItem>
</items>
</Table>



In qtyChanged(), I need to know the row number on which user is editing. How to achieve it?


qtyChanged()





Use the getParent() and reach the row and the row index.

You can achieve it using indexOfItem() of sap.m.Table


indexOfItem()


sap.m.Table


qtyChanged: function(oEvent)
var oRow = oEvent.getSource().getParent();//Get Row
var oTable = oRow.getParent();// Get Table
var iRowIndex = oTable.indexOfItem(oRow);//Get Row index



Note: If the response data is more then table row limit then scroll will appear, then the row index will not work properly.


table row limit



you can get the binding context and then the path. you're also able to get the object itself like this (working example http://jsbin.com/hutuvo/edit?html,output)

sap.ui.define([ "sap/ui/core/mvc/Controller", "sap/ui/model/json/JSONModel"],

var oPageController = Controller.extend("sap.example.Controller",

var oView = this.getView();
oView.setModel(new JSONModel(

,
qtyChanged: function(oEvent)
var oContext = oEvent.getSource().getBindingContext("suppliers");
var oPath = oContext.getPath();
var index = parseInt(oPath.substring(oPath.lastIndexOf("/") + 1), 10);
console.log(index);
console.log(oContext.getObject());

);
return oPageController;
);

var oView = sap.ui.xmlview(
viewContent: jQuery('#oView').html()
);

oView.placeAt('content');

Disagree. A regular OData will have paths whose final part represents the ID of the bound object, not its order in the aggregation. Moreover, he is asking for the row, which is very different from the index of the object in the entity set if the table is scrolled.

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Dynamically update html content plain JS

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
