通过HTML将复杂变量传递给JavaScript的正确方法 [英] Proper way to pass complex variables to javascript through HTML
问题描述
我试图摆脱使用PHP的htmlentities,并停留在这里:
<?php
'echo'< img ... onclick =MP.view(\''。$ i-> name.'\')/>';
?>
但是后来我想,不是替换和检查特殊字符,而只是整个对象的JSON。 p>
<?php
echo'< img ... onclick =MP.view('。json_encode($ i)。')/>';
?>
这提供了一个令人不快的结果,导致大量的双引号。
那么我应该怎么做?我应该为每个图像分配一个数字唯一标识并传递id,然后从JS数组中查找其余的数据吗?
htmlspecialchars(json_encode($ var),ENT_QUOTES,UTF -8)
htmlspecialchars
将任何双引号转换为正确的HTML转义符,使得结果字符串适用于大多数属性。 ENT_QUOTES
参数也可以处理单引号;但你可能不需要你的例子。
I was trying to get away from using PHP's htmlentities and here's where I stopped:
<?php
echo '<img ... onclick="MP.view(\''.$i->name.'\') />';
?>
But then I thought, instead of doing replaces and checks for special characters, I'll just JSON the entire object.
<?php
echo '<img ... onclick="MP.view('.json_encode($i).') />';
?>
And this provided a much undesired result putting in a ton of double quotation marks. So how should I do this? Should I assign a numerical unique id to every image and just pass the id, and then look up the rest of the data from a JS array?
The correct approach in such cases would be:
htmlspecialchars(json_encode($var), ENT_QUOTES, "UTF-8")
htmlspecialchars
turns any double quotes into the proper HTML escapes, making the resulting string suitable for most attributes. The ENT_QUOTES
parameter also takes care of single quotes; but you probably don't need that in your example.
