javascript - breaking main loop - jstree -



javascript - breaking main loop - jstree -

i using jstree library display tree.

in code below, looping through selected nodes in tree , based on conditions, assigning variable 'allow_edit' boolean value.

i break main loop if 'allow_edit = false'.

i tried using label , breaking loop not seem work. getting undefined label.

loop1: $j.each($j("#demo2").jstree("get_selected"), function(index, element) { var selected_node_depth = parseint($j(element).attr('node_depth')); var allow_edit = false; var array_first_filter = $j.grep(array_first, function(v) { homecoming v[1] != "not detected";}) var array_second_filter = $j.grep(array_first_filter, function(v) { homecoming v[3] > selected_node_depth;}) if (array_second_filter.length === 0 || array_second_filter.length == null) { allow_edit = true; } else{ alert("confliction exists in selected terms."); allow_edit = false; //break loop1; /** not working, getting undefined label **/ } }

any suggestions on how break main loop if 'allow_edit = false'? lot

if function pass .each() returns false, iteration stop.

else { allow_edit = false; // pointless since you're homecoming ... homecoming false; }

also, programming style note, construction of form:

if (something) { flag = true; } else { flag = false; }

can improve written simply:

flag = something;

in javascript, force flag boolean (true or false), can this:

flag = !!(something);

the 2 ! (logical "not") operators forcefulness look ("something") evaluated boolean same rules used when look test clause of if statement.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
