使用json_encode输出换行符或换行符？ [英] Output line breaks or new lines with json_encode?

问题描述

我是JSON格式的新手，请原谅我缺乏知识。但不知何故，我需要在我的json_encode数组中添加一些换行符，以便它将使用多行进行解析。我搜索和搜索过，但没有任何东西适合我的情况。

I am new to JSON format so please forgive my lack of knowledge. But somehow, I need to add some line breaks to my json_encode array so that it will parse with multiple lines. I've searched and searched but nothing fits my situation.

输出为：

Following formats accepted: www.website.com website.com website.net/something

但是我想输出这样的数据：

But I'm looking to output the data like this:

Website needs to be in the following formats:  
www.website.com  
website.com  
website.net/something

我试过：

echo json_encode( 
    array( 'status' => 'failed',
           'message' => "Website needs to be in the following formats:\n
            www.website.com\n
            website.com\n
            website.net/something"
    ), JSON_PRETTY_PRINT);

但是Javascript将其解析为文字字符串，因此新行被忽略并输出。我可以使用直接JSON格式将数据从PHP发送到javascript，还是必须使用数组？

But Javascript is parsing it as a literal string so the newlines are ignored and outputted. Can I send the data from PHP to javascript using straight JSON format or do I have to use an array?

我也尝试过使用< ; br /> 。

编辑：

我输出的方式如下：

EDIT :
I am outputting the following way:

$.ajax({
    url: "/forms/content_process.php",
    type:'POST',
    data: $(".content_cat").serialize(),
    processData: false,
    dataType: "json",
    success: function(response) {
        if (response.status == "failed") {
            $(".content_status").css( "background-color", "red" );
            $(".content_status").text(response.message).slideDown("normal");
        } else {
            $(".content_status").css( "background-color", "green" );
            $(".content_status").text("Your category was submitted!").slideDown("normal");
        }
    }
});

推荐答案

使用 \ n 将换行符添加到字符串中。也不要添加真正的换行符。

use \n to insert newline character into the string. don't add a real newline as well.

echo json_encode( 
    array( 'status' => 'failed',
           'message' => "Website needs to be in the following\nformats:\nwww.website.com\nwebsite.com\nwebsite.net/something"
    ), JSON_PRETTY_PRINT);

比将客户端插入dom之前客户端需要用<替换换行符code>< br /> 或使用 white-space：pre 。或者，您可以使用段落< p>< / p> 标记来围绕每一行。这样做看看： jQuery text（）和换行符。

than on the client side before inserting it into your dom, you will need to replace the newlines with <br /> or use white-space: pre. alternatively you could surround each line with paragraph <p></p> tags. to do so have a look here: jQuery text() and newlines.
