我正在使用此代码将textarea
值发送到php
function SendTextArea() {
var hr = new XMLHttpRequest();
var url = "process.php";
var fn = document.getElementById("textarea1").value;
var vars = "txt=" + fn;
hr.open("POST", url, true);
hr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
hr.onreadystatechange = function() {
if (hr.readyState == 4 && hr.status == 200) {
var return_data = hr.responseText;
document.getElementById("state").innerHTML = return_data;
}
}
hr.send(vars);
document.getElementById("state").innerHTML = "wait";
}
运作良好,但我遇到了问题 问题是:当textarea包含" +"时," +"皈依空间" "
<?php
$text = $_POST["txt"];
echo "$text";
?>
答案 0 :(得分:4)
您可以使用encodeURIComponent()
功能解决此问题:
var vars = "txt=" + encodeURIComponent(fn);
