i have 2 buttons , counter, have reset counter every time change button. don't know how reset counter.

var count = 0;  var button1 = document.getelementbyid("button1");  var button2 = document.getelementbyid("button2");  var display = document.getelementbyid("displaycount");    function clickcount(){    count++;    display.innerhtml = count;  }		  button1.onclick = function(){    clickcount();    count=0;  }  button2.onclick = function(){    clickcount();  }

<input type="button" value="button1" id="button1" />  <input type="button" value="button2" id="button2" />  <p>clicks: <span id="displaycount">0</span> times.</p>

pass parameter clickcount function button name, , check if has changed.

var count = 0;  var lastbuttonclicked = "";  var button1 = document.getelementbyid("button1");  var button2 = document.getelementbyid("button2");  var display = document.getelementbyid("displaycount");    function clickcount(buttonname){    if (buttonname === lastbuttonclicked)    {       count++;    }    else    {       count = 1;       lastbuttonclicked = buttonname;    }    display.innerhtml = count;  }		  button1.onclick = function(){    clickcount("1");  }  button2.onclick = function(){    clickcount("2");  }

<input type="button" value="button1" id="button1" />  <input type="button" value="button2" id="button2" />  <p>clicks: <span id="displaycount">0</span> times.</p>
