Update search call back on checkbox change

[abdurrhmansaeed]

Version : jstree-3.3.16-0-gb3135cf I used regexp in search callback and its working if the user input ^ in the field search_callback : function (str, node) { try { return node.data.fullname.match(new RegExp(str)); } catch(ex) { return false; } },

I have a checkbox for using regex (word start with) so I can add ^ in the begging of the search word

	 <input type="text" id="search_word" value="" class="input" style="margin:0em auto 1em auto; display:block; padding:4px; border-radius:4px; border:1px solid silver;" />	
	 <label>start with </label>
	 <input type="checkbox" id="search_start_with" name="search_start_with" value="1" >

If checked the function will add ^ in the begging of the search word I tried several methods but it didn't not work, the last one works if the box is unchecked the checked, but when unchecking it doesn’t work

The code

$(function () {
$('#search_word').keyup(function(){

    $('#ajax').jstree(true).show_all();
	
	var value =  $(this).val();
	
	if($("#search_start_with").is(':checked')){
	
			value = '^'+value ;
		}

				
	$('#search_start_with').change(function() {
	   if($(this).is(":checked")) {
	   
			value = '^'+value ;
			
		$("#ajax").jstree("search",value);
		 return;				
			
	   }
	});

	 $("#ajax").jstree("search", value);
});

});

Can this be solved if the box checked then add ^ else use the search word without it?
