My
code is edited from Thariama in Stackoverflow. His solution
is for “check all values in an array are same”. I changed that to checking to “check
all values in an array are not same”, and apply to a webpage with 4 input box
to test:
<!DOCTYPE html> <html><head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script></head><body>
<input type="text" id="slider_photo_1" /><input type="text" id="slider_photo_2" /><input type="text" id="slider_photo_3" /><input type="text" id="slider_photo_4" /><input type="submit" id="submit" /><script>var img_links = new Array();$("#submit").click(function() { for (var i=0; i<4 ; i++){ var j =i+1; img_links[i] = $("#slider_photo_"+j).val(); } console.log(img_links[0]+" != "+img_links[1]+","+img_links[2]+","+img_links[3]+" ? "+check_nonequal_array_elements(img_links));});
function check_nonequal_array_elements(img_links){ if (img_links.length == 1 || img_links.length == 0) { return true;} //get one element only. for (i=0;i<img_links.length;i++){ if (i > 0 && img_links[i] == img_links[i-1]) { return false;} } return true;}</script></body></html>
Result:
a != b,c,d ? true <- Show all value are not same, In fact really the values are not samea != b,c,c ? false <- Show some values are duplicated. In fact 3rd and 4th are duplicateda != c,c,c ? false <- Show some values are duplicated. 2nd, 3rd and 4th are duplicateda != c,e,c ? true <- Show all value are not same. But 2nd and 4th are duplicated !
And I edited some to fix this problem :
<!DOCTYPE html> <html><head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script></head><body>
<input type="text" id="slider_photo_1" /><input type="text" id="slider_photo_2" /><input type="text" id="slider_photo_3" /><input type="text" id="slider_photo_4" /><input type="submit" id="submit" /><script>var img_links = new Array();$("#submit").click(function() { for (var i=0; i<4 ; i++){ var j =i+1; img_links[i] = $("#slider_photo_"+j).val(); } console.log(img_links[0]+" != "+img_links[1]+","+img_links[2]+","+img_links[3]+" ? "+check_nonequal_array_elements(img_links));});
function check_nonequal_array_elements(img_links){ if (img_links.length == 1 || img_links.length == 0) { return true;} //get one element only. for (i=0; i<img_links.length; i++){ for (j=1; j<img_links.length; j++){ if (i > 0 && img_links[i] == img_links[i-j]) { return false; } } } return true;}</script></body></html>
