PHP Echo的Javascript使用

Question

Using this StackOverflow Question/Answer , I have a Tooltip Javascript that is supposed to use a PHP echo of a session variable. Instead of actually writing out the value, it is writing out the variable name, myvar?

I tried to \\ the echo statement where ' occur with no luck.

Here is the code in question and screenshot of what I'm getting on mouseover:

var ddimgtooltip={

    tiparray:function(){
        var tooltips=[]
        var myvar='<?php echo($row_WADAHTG_ScheduleRequest[\'EmNo\']); ?>';
        tooltips[0]=["image/emp/$myvar.bmp", "$myvar", {background:"#DDECFF", width:"200px"}]
        return tooltips //do not remove/change this line
    }(),

Answer 1

try tho change this:

var myvar='<?php echo($row_WADAHTG_ScheduleRequest[\'EmNo\']); ?>';
tooltips[0]=["image/emp/$myvar.bmp", "$myvar", {background:"#DDECFF", width:"200px"}]

to this:

var myvar='<?php echo($row_WADAHTG_ScheduleRequest[\'EmNo\']); ?>';
tooltips[0]=["image/emp/" + myvar + ".bmp", myvar, {background:"#DDECFF", width:"200px"}]

you have already your php value into myvar so you don't need to use $myvar as in php but only myvar for javascript

Answer 2

try:

var myvar='<?php echo($row_WADAHTG_ScheduleRequest[\'EmNo\']); ?>';
tooltips[0]=["image/emp/" + myvar + ".bmp", myvar, {background:"#DDECFF", width:"200px"}]
