tengo dos matrices
const originalArray= ["form1","form2","form3","form4","form5"]; const modifiedArray = ["form2","additionForm1","form1","form3","additionForm2"];resultados esperados es,
let testScript = [form1 is moved to position 2, form2 is moved to position 0, form3 is moved to position 3, from 4 is deleted position is 3] form5 is deleted position is 4, additional1 added to position 1 additional2 added to position 4 ]Puedo obtener datos eliminados usando el siguiente código, pero cuando intento mover datos y cambiar la posición de los datos, me encontré con un problema.
esto es lo que probé,
function testFunc(){ const originalArray = ["form1","form2","form3","form4","form5"]; const modifiedArray= ["form2","additionForm1","form1","form3","additionForm2"]; let flag = false; let result = []; originalArray.forEach((Nelement, Nindex) => { modifiedArray.forEach((Telement, Tindex) => { if(Nelement === Telement){ //check originalArray data containg the modified array flag = true; //return false; } if(flag === true && Nindex !== Tindex){ //try to get moved data result.push(Nelement+" change the position to "+ Tindex ) } }) if(flag !== true){ //if original array data doesn't include in modified array result.push(Nelement+" removed from "+ Nindex + " position" ) } flag = false }) }Esta es una pregunta interesante. Esto debería funcionar y el resultado es
"form1 se mueve a la posición 2",
"form2 se mueve a la posición 0",
"form3 se mueve a la posición 3",
"form4 se elimina la posición es 3",
"form5 se elimina la posición es 4",
"additionForm1 agregado a la posición 1",
"additionForm2 añadido a la posición 4"
Uso otro ciclo para mostrar los elementos agregados a la matriz.
const originalArray = ["form1","form2","form3","form4","form5"]; const modifiedArray= ["form2","additionForm1","form1","form3","additionForm2"]; let flag = false; let result = [] function testFunc(){ //Find added items between the two lists originalArray.forEach((Nelement, Nindex) => { modifiedArray.forEach((Telement, Tindex) => { if(Nelement === Telement){ //check originalArray data containg the modified array flag = true; if(Nindex !== Tindex)//try to get moved data result. push(Nelement+" is moved to position "+ Tindex ) } }) if(!flag){ //if original array data doesn't include in modified array result.push(Nelement+" is deleted position is "+ Nindex) } flag = false }) //check added item let arr = modifiedArray.filter(x => !originalArray.includes(x)); for(let j in arr) result.push(arr[j]+" added to position "+modifiedArray.indexOf(arr[j])) console.log(result) } testFunc()simplemente reemplace el siguiente fragmento
if(flag === true && Nindex !== Tindex){ //try to get moved data result.push(Nelement+" change the position to "+ Tindex ) }a
if(Nelement === Telement && Nindex !== Tindex){ //try to get moved data result.push(Nelement+" change the position to "+ Tindex ) } Esto se debe a que flag no se desarma en el segundo bucle.
solución completa a continuación.
function testFunc(){ const originalArray = ["form1","form2","form3","form4","form5"]; const modifiedArray= ["form2","additionForm1","form1","form3","additionForm2"]; let flag = false; let result = []; originalArray.forEach((Nelement, Nindex) => { modifiedArray.forEach((Telement, Tindex) => { if(Nelement === Telement){ //check originalArray data containg the modified array flag = true; //return false; } if(Nelement === Telement && Nindex !== Tindex){ //try to get moved data result.push(Nelement+" change the position to "+ Tindex ) } }) if(flag !== true){ //if original array data doesn't include in modified array result.push(Nelement+" removed from "+ Nindex + " position" ) } flag = false; }) return result; }
