我可以从php函数触发javascript函数吗？

Question

I am getting html data through js ajax function like this

function getData(dataSource,datasend)
{ 

var XMLHttpRequestObject = false; 

if (window.XMLHttpRequest) {
XMLHttpRequestObject = new XMLHttpRequest();
} else if (window.ActiveXObject) {
XMLHttpRequestObject = new 
ActiveXObject("Microsoft.XMLHTTP");
}

if(XMLHttpRequestObject) {
XMLHttpRequestObject.open("POST", dataSource, true); 
XMLHttpRequestObject.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
XMLHttpRequestObject.send('data='+escape(datasend));

XMLHttpRequestObject.onreadystatechange = function() 
{ 
    if (XMLHttpRequestObject.readyState == 4 && XMLHttpRequestObject.status == 200) { 
        document.getElementById(datafin).innerHTML = XMLHttpRequestObject.responseText;
            //when the html has require data extecute this function
            if(html has needed data for the function){
                foo();
            }

    }
} 

function foo(){
     //stuff to do with the html when loaded
}

as far as i do it the html is generated by a php function. Now Is there way to trigger the foo() function in the html data generated or a way to send data that can trigger the function. Thanks

You can use like,

in php file,

 echo '<script>foo();</script>';

javscript,

  function foo(){
     //stuff to do with the html when loaded
     alert('test');
  }
