php - How to use txt content to onclick="doAjaxCall(' ')? -

i use voice xml select logo or movie. put logo.svg or movie.php in txt file. use php load logo.svg or movie.php $thedata.

<?php ini_set("display_errors", true);  // define file name variable $myfile = "voice.txt";  // file handle file: 'r' means set permission read $fh = fopen($myfile, 'r');  //read entire file , store contents in variable $thedata $thedata = fread($fh, filesize($myfile));  // close file ok use later fclose($fh);  //echo  whatever in file browser echo $thedata;    // part 2 // file handle file: 'a' means set permission read $fh = fopen($myfile, 'w') or die("error trying open a");  $nodata = "no msgs";  //read entire file , store contents in variable $thedata $thedata = fwrite($fh, $nodata);  // close file ok use later fclose($fh)  ?> 

now want show either of them on webs. use:

<input class="logo" type="button" value="call (832) 271-6319 " onclick="doajaxcall('  ');"/> 

how can it? should use javascript?

i'm not sure want achieve. onclick allows add javascript function

<input onclick="myfunction()" /> 

you can make ajax call function. or can use jquery , attach function input click event.

$(".logo").click(function(){ ..... });
