javascript - 参数编码(引号和空格字符)

Question

所以我向 JavaScript 函数发送一个字符串参数，问题是空格字符和/或引号。我可以让其中一种方式工作，但不知道如何让两种方式同时工作。

我将encodeURIComponent 和decodeURIComponent 保留在我的示例中，因为我当前使用它们来处理空格。

Javascript:

function alertTitle(title){
    alert(decodeURIComponent(title));
}

PHP:

//...fetching from MySQL
$title = $row['title'];

//If $title content is wrapped in single or double quotes, this will do:
$title = str_replace("\"",""",$row['title']);
//But if it's not, and has spaces, I have to wrap it in quotes for encodeURIComponent:
$title = '\''.$row['title'].'\''; 
//And that obviously gives error in encodeURIComponent if $title happens already to have
// single quotes

//..And sending $title to javascript:
echo '<a onclick="alertTitle(encodeURIComponent('.$title.'));" href="#">Alert</a>';

所以不知何故我也需要转义单引号，或者然后想出一些非常不同的方法。 但这已经很接近了，所以我希望我只是错过了一些简单的事情。

$title 可能是以下示例中的任何一种:

"Title"

"Title with spaces"

'Title'

'Title' with "all combined"

Title "Blaablaa" here

等等。

我们非常欢迎所有提示。谢谢!

只需使用单引号添加预替换:)

//...fetching from MySQL
$title = $row['title'];

//If $title content is wrapped in single or double quotes, this will do:
$title = str_replace("\"",""",$row['title']);
$title = str_replace("\'","'",$row['title']);

//But if it's not, and has spaces, I have to wrap it in quotes for encodeURIComponent:
$title = '\''.$row['title'].'\''; 
//And that obviously gives error in encodeURIComponent if $title happens already to have
// single quotes

//..And sending $title to javascript:
echo '<a onclick="alertTitle(encodeURIComponent('.$title.'));" href="#">Alert</a>';
