用jQuery检索包含换行符的JSON格式的文本时出现问题 [英] Problem when retrieving text in JSON format containing line breaks with jQuery

问题描述

在检索JSON格式的文本时遇到一个奇怪的问题.我使用jQuery post将一些数据(也是JSON格式)发送到服务器(运行PHP)，效果很好.然后，当我使用jQuery get从服务器请求相同的数据时，回调方法将永远不会执行.仅当数据为JSON格式且数据包含换行符时，才会发生这种情况.当我不使用JSON格式时，它可以正常工作.让我感到困惑的是，上传数据没有问题.

I'm having a strange problem when retrieving JSON formatted text. I use jQuery post to send some data (also JSON formatted) to the server (running PHP) which works fine. Then, when I request the same data from the server using jQuery get, the callback method never executes. This only occurs when the data is JSON formatted and the data contains a line break. When I don't use JSON formatting it works fine. What baffles me is that there are no problems with uploading the data.

上传代码:(有效)

$.post("ajax/contents_ajax.php", {
    'title': caption,
    'text': frameText().getContent(),
    'image_id': img
},
//Callback

下载代码:(不适用于换行符)

Download code: (doesn't work with line breaks)

$.get("ajax/contents_ajax.php", { 'get_item': id },
function (data){
    //Never gets executed if data contains line breaks
}
,'json');

整个问题源于一个事实，即使我启用了该选项，TinyMCE富文本编辑器似乎仍然坚持在所有位置插入换行符

The whole problem stems from the fact that the TinyMCE rich text editor seems to insist on inserting line breaks everywhere, even though I enabled the option

remove_linebreaks : true

我确实希望有换行符，但如果它们破坏了我的代码，则不行.谁能告诉我这里的问题是什么，也许我可以如何使用PHP在服务器上编码换行符?

I do prefer to have line breaks, but not if they break my code. Can anyone tell me what the problem is here, and perhaps how I can encode the linebreaks on the server with PHP?

尽管用''替换'\n'的建议不起作用，但它接近正确的解决方案.这段代码删除了令人反感的字符:

While the suggestions to replace '\n' with '' did not work, it was close to the right solution. This code removed the offending characters:

function parse($text){
    $parsedText = str_replace(chr(10), "", $text);
    return str_replace(chr(13), "", $parsedText);

}

推荐答案

如果您想保持换行，可以尝试:

If you would like to keep the line breaks, you might try:

function parse($text) {
    // Damn pesky carriage returns...
    $text = str_replace("\r\n", "\n", $text);
    $text = str_replace("\r", "\n", $text);

    // JSON requires new line characters be escaped
    $text = str_replace("\n", "\\n", $text);
    return $text;
}
