with an entry type
of "mark
" will be removed from the performance entry buffer.
performance.clearMarks(); performance.clearMarks(name);
DOMString
representing the name of the timestamp. If this argument is omitted, all performance entries
with an entry type
of "mark
" will be removed.The following example shows both uses of the clearMarks()
method.
function clear_mark(name) { if (performance.clearMarks === undefined) { console.log("performance.clearMarks Not supported"); return; } // Remove all "mark" performance entry types with the specified name performance.clearMarks(name); } function clear_all_marks() { if (performance.clearMarks === undefined) { console.log("performance.clearMarks Not supported"); return; } // Remove all "mark" type performance entries from the performance buffer performance.clearMarks(); }
