你如何处理'，在php，javascript中人名中的单引号 [英] How do you deal with ', single quote in person's names in php, javascript

问题描述

我注意到某些名称条目(例如 O'Rourke 或 O'reilly)在某些情况下会破坏 javascript.我想知道你是怎么处理的.我从 PHP/MYSQL 中提取这些名称并将它们放入 javascript 中.

I noticed that some of name entries, like O'Rourke or O'reilly breaks javascript in some cases. I wonder how you deal with it. I pull these names out of PHP/MYSQL and put them in javascript.

你是在进入数据库之前还是在退出数据库之后替换它们?

Do you replace them before entering to database or after pulling out of database?

推荐答案

为了输出一个 javascript 变量，您正在经历大量混乱且容易出错的字符串附加工作.你应该做的是在 PHP 中构建你想要的数据结构(一个数组数组)，然后使用 json_encode() 来发出一个与 javascript 兼容的文字.所有引号等都会被编码器自动转义.

You're going through a lot of messy and error-prone string-appending work just to output a javascript variable. What you should do instead is build the data structure you want in PHP (an array of arrays) and then use json_encode() to emit a javascript-compatible literal. All quotes and such will be automatically escaped by the encoder.

$itemOutput = array();
if(count($items)) {
    foreach($items as $item) {
        foreach($advisors as $key=>$advisor) {
            if($item['advisor']==$advisor['id']) {
                $ad=$advisor['last_name'];
            }
        }
        $active_icon = ($item['active']=='1'?'tick':'cross');
        $editlink = anchor('auth/admin/members/form/'.$item['id'],$this->bep_assets->icon('pencil'));
        $itemOutput[] = array(
            $item['first_name'],
            $item['last_name'],
            $item['email'],
            $item['parent_email'],
            $item['parent_email2'],
            $ad,
            $this->beep_assets->icon($active_icon),
            $editLink
        );
    }
}
echo "data.addRows(" . json_encode($itemOutput) . ");" ;

如果你有一个对象或一个关联数组，它会作为一个 javascript 对象发出:

If you have an object or an associative array, it gets emitted as a javascript object:

echo json_encode( 
    array( 'a'=>'aa', 'b'=>'bb'),
    array( 'c'=>'cc', 'd'=>'dd')
);
==> [{"a":"aa","b":"bb"},{"c":"cc","d":"dd"}]
