Two parameters in javascript

Question

I want to send two php values to a javascript function. Apparently it doesn't do anything. Is my syntax correct?

<script>
function onmouseclick(nr, name){
        alert(nr);
        alert(name);
    }
</script>

<?php
echo '<img onClick="javascript: onmouseclick('. $template->id .','. $template->name .');" "class="img" />';
?>

Answer 1

您应该添加引号：

echo '<img onClick="javascript: onmouseclick("'. $template->id .'", "'. $template->name .'");"

Answer 2

Yes you need to use as

echo '<img onClick="javascript: onmouseclick(\''. $template->id .'\',\''. $template->id .'\');" class="img" />';

Need to add the param inside quotes ' ' but since you are doing echo '...' you need to use escape \\ so that the quotes are treated as string.

Answer 3

just use without php tags

<img onClick="javascript:onmouseclick('<?php echo $template->id;?>','<?php echo $template->name;?>');" class="img" />

or with php tags

echo '<img onClick="javascript: onmouseclick("'. $template->id .'", "'. $template->name .'");"

Answer 4

您可以使用它来避免字符逃脱

echo sprintf('<img onclick="%s" class="img"/>',sprintf("onmouseclick(%d,'%s');",$template->id,$template->id));
