Call JavaScript function(with parameters) by onclick event

Question

I cant use PHP variables to use as parameters for my function.

The function is:

<script type="text/javascript">
function myFunction(id,name) {
    alert(id);
    alert(name);
}
</script>

And this is PHP part:

echo "<button onclick='myFunction($intvar,$strvar)' type='button'>ClickMe</button>";

the call works when I use numbers like this: myFunction(0,1) but I need to use variables to call myFunction.

Please Help, thanks.

Answer 1

好的做法是回显json编码的变量版本，这样就可以确保字符串被正确引用：

echo "<button onclick='myFunction(" . json_encode($intvar) . "," . json_encode($strvar, JSON_HEX_APOS) . ")' type='button'>ClickMe</button>";

Answer 2

你试试这个function myFunction(ide,name) { change insted of id => ide echo "<button onclick='myFunction(".'"'.$intvar.'","'.$strvar.'"'.")' type='button'>ClickMe</button>";
