问题描述
我想送一些变量和一个字符串与JavaScript的POST方法。我从数据库中获取的字符串,然后将其发送到PHP页面。我使用XMLHtt prequest对象。的问题是该字符串中包含的字符与&几声,$ _ POST数组在PHP中看到它像多个密钥。我试图取代&放大器;用\&安培;替换()函数,但似乎并没有做任何事情。任何人都可以帮忙吗?
JavaScript的code和字符串看起来是这样的:
VAR所见即所得= dijit.byId(所见即所得)获得(价值)。
变种wysiwyg_clean = wysiwyg.replace('&安培;','\&安培;');
VAR poststr =ACT =保存;
poststr + =&放大器; titlu =+ frm.value.titlu;
poststr + =&放大器; sectiune =+ frm.value.sectiune;
poststr + =&放大器;所见即所得=+ wysiwyg_clean;
poststr + =&放大器; id_text =+ frm.value.id_text;
xmlhttp.open(POST,lista_ajax.php,真正的);
xmlhttp.setRequestHeader(内容型,应用程序/ x-WWW的形式urlen codeD);
xmlhttp.send(poststr);
字符串为:
<跨度类=蓝紫魅力>&安培; QUOT; Busola和放大器; QUOT;< / SPAN>
您可以使用<一个href="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/en$c$cURIComponent">en$c$cURIComponent().
这会逃避所有的网址不能逐字出现字符:
VAR wysiwyg_clean = EN codeURIComponent(所见即所得);
在这个例子中,符号字符&安培;
将被转义序列替换%26
,这是有效的网址。
I want to send a few variables and a string with POST method from JavaScript. I get the string from the database, and then send it to a PHP page. I am using XMLHttpRequest object.The problem is that the string contains the character "&" few times, and $_POST array in PHP sees it like multiple keys.I tried replacing the "&" with "\&" with replace() function, but doesn't seem to do anything.Can anyone help?
The javascript code and the string looks like this:
var wysiwyg = dijit.byId("wysiwyg").get("value");
var wysiwyg_clean = wysiwyg.replace('&','\&');
var poststr = "act=save";
poststr+="&titlu="+frm.value.titlu;
poststr+="§iune="+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);
String is:
<span class="style2">"Busola"</span>
You can use encodeURIComponent().
It will escape all the characters that cannot occur verbatim in URLs:
var wysiwyg_clean = encodeURIComponent(wysiwyg);
In this example, the ampersand character &
will be replaced by the escape sequence %26
, which is valid in URLs.
