I have the following if condition that checks if the a value entered in a form exists in another sheet and if thats the case it will display an alert to the user, but i also wanted to check if the value was found in another sheet that the cell next to it is not empty
var valueToSearch2 = formS.getRange("B5").getValue();
var logSValues = logS.getDataRange().getValues();
if(logSValues.filter(row => row.includes(valueToSearch2)).length)
{
SpreadsheetApp.getUi().alert("Stop Processing");
return
}

Answer 1

Try this:
function checkTheEntireSheet() {
const ss = SpreadsheetApp.getActive();
const formS = ss.getSheetByName('Sheet0');
const vts = formS.getRange("B5").getValue();
const logS = ss.getSheetByName('Sheet1');
let tf = logS.createTextFinder(vts).findAll();
if (tf.length > 0) {
SpreadsheetApp.getUi().alert("Stop Processing");
}
}

Answer 2

const valueToSearch2 = formS.getRange("B5").getValue();
const logSValues = logS.getDataRange().getValues();
const found = logSValues.some(row => {
const foundIndex = row.findIndex(cell=>cell==valueToSearch2)
if(foundIndex<0){
return false // search term not found
}
const emptyRight = !row[foundIndex+1]
const emptyLeft = foundIndex>0 && !row[foundIndex-1]
// additional condition, must be also empty either to the right or to the left
return emptyLeft || emptyRight
})
if(found){
SpreadsheetApp.getUi().alert("Stop Processing");
return
}
