I want to check if a string like "me and her" contains a value from an array. The array could look like:
[" and ", "Mr", "sir"]
If it does it should return false. That means that "John Doe" should return true but "Mr. John Doe" or "john and Jane Doe" should return false
I don't think I can use $.inArray as it only checks for the specific value and not part of the string.
Anyone?
You can use the native JavaScript String.includes() method to check if a string includes a value, then loop through your list of things. Something like this:
function checkStringAgainstList(str) {
var exclude = ['Mr', 'and', 'Mrs'];
for (var ndx in exclude) {
if(str.includes(exclude[ndx])) {
return false;
}
}
return true;
}
This seems like what you want. Here's a fiddle
This should be the kind of thing you are looking for:
var myArray = ["Mr", "and", "Sir"];
function checkForString(inputString) {
var runningTotal = 0;
//For loop to check each item of the array against the string, to see if it appears
for (var i = 0; i < myArray.length; i++) {
runningTotal += inputString.toLowerCase().indexOf(myArray[i].toLowerCase());
}
//Check the running total. Each term that DOESN'T appear in the string, returns -1, so multiply by the array length to find the value if none of the items in the array appear in the string
if (runningTotal == (myArray.length * -1)) {
return true;
} else {
return false;
}
}
console.log('Mr John Doe = ' + checkForString("Mr John Doe"))
console.log('John Doe = ' + checkForString("John Doe"));
