問題描述

我想用 JavaScript 的 POST 方法發送一些變量和一個字符串.

I want to send a few variables and a string with the POST method from JavaScript.

我從數據庫中獲取字符串，然后將其發送到 PHP 頁面.我正在使用 XMLHttpRequest 對象.

I get the string from the database, and then send it to a PHP page. I am using an XMLHttpRequest object.

問題是字符串多次包含字符&，而PHP中的$_POST數組把它看成是多個鍵.

The problem is that the string contains the character & a few times, and the $_POST array in PHP sees it like multiple keys.

我嘗試將 & 替換為 & 與 replace() 函數，但它似乎沒有做任何事情.

I tried replacing the & with & with the replace() function, but it doesn't seem to do anything.

誰能幫忙?

javascript 代碼和字符串如下所示:

var wysiwyg = dijit.byId("wysiwyg").get("value");
var wysiwyg_clean = wysiwyg.replace('&','&');

var poststr = "act=save";

poststr+="&titlu="+frm.value.titlu;
poststr+="&sectiune="+frm.value.sectiune;
poststr+="&wysiwyg="+wysiwyg_clean;
poststr+="&id_text="+frm.value.id_text;

xmlhttp.open("POST","lista_ajax.php",true);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send(poststr);

字符串是:

 <span class="style2">&quot;Busola&quot;</span>

推薦答案

你可以使用 encodeURIComponent().

它將轉義所有不能在 URL 中逐字出現的字符:

It will escape all the characters that cannot occur verbatim in URLs:

var wysiwyg_clean = encodeURIComponent(wysiwyg);

在此示例中，與字符 & 將被替換為轉義序列 %26，這在 URL 中有效.

In this example, the ampersand character & will be replaced by the escape sequence %26, which is valid in URLs.
