I would like the function to return the result of this action on the values ​​from the table below:




a+b*c-(e/f)




This action is worked whithout row with e and f. I found similar problem here but there is no solution for this one special last row. I'm shure how i should get value from e and f inputs. The function shul be workinf for each row - no matter how many of them will be.






function calc(id) {

  var row = id.parentNode.parentNode;

  var a = row.cells[0].getElementsByTagName('input')[0].value;

  var b = row.cells[1].getElementsByTagName('input')[0].value;

  var c = row.cells[2].getElementsByTagName('input')[0].value;

  var e = row.cells[0].getElementsByTagName('input')[1].value; //not working

  var f = row.cells[1].getElementsByTagName('input')[1].value; //not working



  var res = +a + +b * c - (e / f);



  row.cells[3].getElementsByTagName('input')[0].value = res;

}

share|improve this question















I would like the function to return the result of this action on the values ​​from the table below:




a+b*c-(e/f)




This action is worked whithout row with e and f. I found similar problem here but there is no solution for this one special last row. I'm shure how i should get value from e and f inputs. The function shul be workinf for each row - no matter how many of them will be.






function calc(id) {

  var row = id.parentNode.parentNode;

  var a = row.cells[0].getElementsByTagName('input')[0].value;

  var b = row.cells[1].getElementsByTagName('input')[0].value;

  var c = row.cells[2].getElementsByTagName('input')[0].value;

  var e = row.cells[0].getElementsByTagName('input')[1].value; //not working

  var f = row.cells[1].getElementsByTagName('input')[1].value; //not working



  var res = +a + +b * c - (e / f);



  row.cells[3].getElementsByTagName('input')[0].value = res;

}

UPDATE
I wrote a function that was supposed to count the values ​​for data from lines with variables e and f. But unfortunately it lacks to be performed for all rows? I'm not shure how set numbers of rows to serve?






function calc(element) {

  var row = element.parentNode.parentNode;

  var a = row.cells[0].getElementsByTagName('input')[0].value;

  var b = row.cells[1].getElementsByTagName('input')[0].value;

  var c = row.cells[2].getElementsByTagName('input')[0].value;



  // Getting the last row

//  var lastRow = document.getElementById("last-values");



  // Then, retrieving e and f

  //var e = lastRow.cells[1].getElementsByTagName('input')[0].value;

  //var f = lastRow.cells[3].getElementsByTagName('input')[0].value;



  var res = +a + +b * c;



  row.cells[3].getElementsByTagName('input')[0].value = res;

}



function lastEle()

{	

		var y = document.getElementById('e').value;

		var z = document.getElementById('f').value;

		

		var mytable = document.getElementById('myTable');

		var myinputs = mytable.getElementsByTagName('input');

		var rowy = mytable.rows.length;

		

		for (var i = 1; i < mytable.rows.length; i++) {

		

		var tmp = mytable.rows[i].myinputs[3].value;

		var wynik = +y + +z + +tmp;

		mytable.rows[i].myinputs[4].value = wynik;

}

You did this:



<table>

    <tr>

        <td><input type="text" /></td>

        <td><input type="text" /></td>

        <td><input type="text" /></td>

        <td><input type="text" /></td>

    </tr>

</table>


Assuming row points to <tr>, you can access them this way, where x is the (n+1)th cell and y the (n+1)th input data :



row.cells[x].getElementsByTagName('input')[y];


Here, y could only equal 0, because there is only one input element embedded in the td element.
To access the "e and f" row, simply set an id to their row:



<tr id="last-values">

    <!--  e  -->

    <th>e</th>

    <td><input type="text" value="5" /></td>

    <!--  f  -->

    <th>f</th>

    <td><input type="text" value="6" /></td>

  </tr>


Then, rewrite your calc() function:



function calc(element) {

  var row = element.parentNode.parentNode;

  var a = row.cells[0].getElementsByTagName('input')[0].value;

  var b = row.cells[1].getElementsByTagName('input')[0].value;

  var c = row.cells[2].getElementsByTagName('input')[0].value;



  // Getting the last row

  var lastRow = document.getElementById("last-values");



  // Then, retrieving e and f

  var e = lastRow.cells[1].getElementsByTagName('input')[0].value;

  var f = lastRow.cells[3].getElementsByTagName('input')[0].value;



  var res = +a + +b * c - (e / f);



  row.cells[3].getElementsByTagName('input')[0].value = res;

}


Keep in mind that you should write another function if e or f are updated: in this case, you'll have to loop the whole rowset to update the values. I let you write this part.



Below a working snippet (without the part of e and f updating).






function calc(element) {

  var row = element.parentNode.parentNode;

  var lastRow = document.getElementById("last-values");

  var a = row.cells[0].getElementsByTagName('input')[0].value;

  var b = row.cells[1].getElementsByTagName('input')[0].value;

  var e = lastRow.cells[1].getElementsByTagName('input')[0].value;

  var f = lastRow.cells[3].getElementsByTagName('input')[0].value;

  • I think and understand your concept but do not you think it will look ugly? will it be a bad idea to get values from e and f in this way {var e = document.getElementById('e').value;}

  • I would like to retrive e from input next to field with E on gray back-ground and the same way f. E and F they are additional variables to which the above rows must refer in the table

Trompette piccolo

Image
Ne doit pas être confondu avec trompette de poche. Trompette piccolo en si bémol, avec des branches d'embouchure différentes pour le si bémol (la plus courte) ou la (la plus longue) Trompette piccolo La trompette piccolo est la plus petite de la famille des trompettes. Elle joue une octave plus haut que la trompette standard en si bémol. La plupart des trompettes piccolo sont conçues pour jouer dans les deux tonalités de si bémol ou la, en utilisant une branche d'embouchure différente pour chaque tonalité. Le tube de la trompette piccolo en si bémol a une longueur moitié de celle de la trompette normale en si bémol. Des trompettes piccolo en sol, fa, ut sont également fabriquées, mais elles sont rares. La trompette soprano en ré, aussi connu comme la « trompette Bach », a été inventée vers 1890 par le facteur belge Victor-Charles Mahillon pour jouer les parties hautes de la trompette dans la musique de Bach et Haendel.

Slow SSRS Report in dynamic grouping and multiple parameters

Image
0 I have developed a report which has 5 dynamic row groups from where users can choose in parameter selection. The report has 12 parameters so that user can get required information as per their parameter choice. Each parameter has multi value selection option with numerous lists of values (example: Customer parameter has 35,000 values and Item parameter has 2,500 values). Now, the report takes huge time to load parameter values as well as slow in preview (although, server resource is adequate). I am looking for a solution to improve the parameter selection performance without reducing the number of parameter and dynamic grouping sql-server reporting-services ssrs-2012 share | improve this question
