if statement not working

[etsted]

when i console.log the str variable it says "No suggestions", but when i try to use that statement in a if statement it doesnt work.

var suggested_titels = ajax.responseText.split("S_E_C_R_E_T__S_I_G_N__!_|_!_|");                              for(var i =0;i < suggested_titels.length; i++){                           var space = document.createElement("BR");              var node = document.createElement("SPAN");              var textnode=document.createTextNode(suggested_titels[i]);              var check = document.createTextNode(suggested_titels[0]);              var str = document.createElement("DIV");              str.appendChild(check);              node.appendChild(textnode);             node.appendChild(space);              sQ.appendChild(node);              if(suggested_titels[0] == "No suggestions"){                  sQ.innerHTML = "";              }          }            console.log(str);

sQ is supposed to get empty when there is not suggestions in the DB

So IF ajax return with only "No suggestions" which when split its index will be suggested_titels[0] you want sQ whatever that is? to be empty? but still create br, span and the rest

          for(var i =0;i < suggested_titels.length; i++){ //length will be 1 which will equal "No suggestions"                           var space = document.createElement("BR"); //still create br              var node = document.createElement("SPAN"); // still create span              var textnode=document.createTextNode(suggested_titels[i]); //still create text node of "No suggestions" as this will be the only text returned              var check = document.createTextNode(suggested_titels[0]); // still ditto              var str = document.createElement("DIV"); //still create div              str.appendChild(check); // still append to div - check -> "No suggestions"              node.appendChild(textnode); //still append to span - textnode ->  "No suggestions"             node.appendChild(space); //still append to span - space -> "<br>"              sQ.appendChild(node); //still append to sQ? - span with textnode ->  "No suggestions" + "<br>"              if(suggested_titels[0] == "No suggestions"){ // if suggested_titels[0] matches "No suggestions"                  sQ.innerHTML = ""; // sQ whatever that is will be cleared.              }          }

IS this right?

yes that is right. You can get a clear demonstration at my website widegrass.com. Search for "n" using my search bar, then add more "n" and see what happen

In the code you have posted above it doesn't make any sense to have the "if" inside the for-loop.
