Bootstrap Typeahead Not Showing Suggestion Which Have The Valuekey Starting With Same Value

I'm using typeahead v0.11.1 to show the result but it is not showing the result which have result starting with the same result. The result I am getting from database is this : Ob

Solution 1:

Note, Not certain about expected result of

$("#PositionId").val("");

? ; html not appear at Question ; .typeahead() appear to be initialized at

$("#Position")

element , without "Id" within selector string ?

---

The problem is typeahead is displaying all the result except Sr. Android Developer and Sr. iOS Developer

Appear due to period character . within string value of Title property of returned obeject . .typeahead appear to match exact input value of query . e.g.,; if query was "sr" .typeahead would not match "Sr." ; if query was "sr." .typeahead would match "Sr. Android Developer" , "Sr. iOS Developer" . Adjusted test for returned matches that would be displayed within templates , within filter function at Bloodhound initialization ; removed period character "." from match test before results returned to templates. If query is "sr" , should return both "Sr. Android Developer" , "Sr. iOS Developer" . If query is "sr ios" , should return "Sr. iOS Developer" to templates for display as suggestion .

Try creating setting Bloodhound.tokenizers.obj.whitespace to "value" ; returning object to templatessuggestion callback function within filter at Bloodhound inititalization ; returning "suggestion" html at templatessuggestion callback function , utilizing object passed at filter within Bloodhound initialization
