无法使用JQuery在新的浏览器窗口中显示PHP脚本生成的HTML代码

Question

我编写了一个名为generateemail.php的PHP脚本，该脚本接受用户的输入，然后将其输入与模板结合在一起，以构成一个完整的HTML页面，准备发送给客户。

问题是我希望脚本打开显示内容的单独浏览器窗口-我可以使代码传递到新窗口，但是它显示为代码，而不是如屏幕截图所示实际处理。

 <script> function htmlEntities(str) { return String(str).replace('&amp;', '&').replace('&lt;', '<').replace('&gt;', '>').replace('&quot;', '\\"'); } function printClick() { var w = window.open(); var html = "<?php echo preg_replace( "/\\r|\\n/", "", htmlspecialchars($emailheader) ); ?>"; var html2 = "<?php echo preg_replace( "/\\r|\\n/", "", htmlspecialchars($emailbody) ); ?>"; // how do I write the html to the new window with JQuery? $(w.document.head).html(html).val(); $(w.document.body).html(html2).val(); } </script>

Answer 1

像这样尝试一下http://jsfiddle.net/ty368zfr/

您不能使用jQuery，所以请使用纯JavaScript

 w.document.head.innerHTML = html;
 w.document.body.innerHTML = html2;

Answer 2

我认为问题是您的html字符串的连贯性。 尝试这样的事情：

var html = '<?php echo preg_replace( "/\\r|\\n/", "", htmlspecialchars($emailheader) ); ?>';
var html2 = '<?php echo preg_replace( "/\\r|\\n/", "", htmlspecialchars($emailbody) ); ?>';

您还应该删除val()函数调用。 无需放置您的html代码！

$(w.document.head).html(html);
$(w.document.body).html(html2);

Answer 3

问题是您正在使用htmlspecialcharacter对html进行编码。 有一种解决方案将其删除

<?php
$emailheader="<meta charset='utf-8' /><title>Sample header</title>";
$emailbody="<p>Some body</p>";
?>

    <script>
        var w = window.open();

      var html = "<?php echo preg_replace( "/\r|\n/", "", htmlspecialchars($emailheader) ); ?>";
      var html2 = "<?php echo preg_replace( "/\r|\n/", "", htmlspecialchars($emailbody) ); ?>";

     console.log(html);//Result :  &lt;meta charset='utf-8' /&gt;&lt;title&gt;Sample header&lt;/title&gt;

      var html = "<?php echo preg_replace( "/\r|\n/", "", $emailheader ); ?>";
      var html2 = "<?php echo preg_replace( "/\r|\n/", "", $emailbody ); ?>";

      console.log(html);//Result : <meta charset='utf-8' /><title>Sample header</title>

        w.document.head.innerHTML = html;
        w.document.body.innerHTML = html2;
    </script>

我设法通过使用Base64解决了该问题

<script>


var Base64 = {

    _keyStr: "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=",

    decode: function(input) {
        var output = "";
        var chr1, chr2, chr3;
        var enc1, enc2, enc3, enc4;
        var i = 0;

        input = input.replace(/[^A-Za-z0-9\+\/\=]/g, "");

        while (i < input.length) {

            enc1 = this._keyStr.indexOf(input.charAt(i++));
            enc2 = this._keyStr.indexOf(input.charAt(i++));
            enc3 = this._keyStr.indexOf(input.charAt(i++));
            enc4 = this._keyStr.indexOf(input.charAt(i++));

            chr1 = (enc1 << 2) | (enc2 >> 4);
            chr2 = ((enc2 & 15) << 4) | (enc3 >> 2);
            chr3 = ((enc3 & 3) << 6) | enc4;

            output = output + String.fromCharCode(chr1);

            if (enc3 != 64) {
                output = output + String.fromCharCode(chr2);
            }
            if (enc4 != 64) {
                output = output + String.fromCharCode(chr3);
            }

        }

        output = Base64._utf8_decode(output);

        return output;

    },

    _utf8_decode: function(utftext) {
        var string = "";
        var i = 0;
        var c = c1 = c2 = 0;

        while (i < utftext.length) {

            c = utftext.charCodeAt(i);

            if (c < 128) {
                string += String.fromCharCode(c);
                i++;
            }
            else if ((c > 191) && (c < 224)) {
                c2 = utftext.charCodeAt(i + 1);
                string += String.fromCharCode(((c & 31) << 6) | (c2 & 63));
                i += 2;
            }
            else {
                c2 = utftext.charCodeAt(i + 1);
                c3 = utftext.charCodeAt(i + 2);
                string += String.fromCharCode(((c & 15) << 12) | ((c2 & 63) << 6) | (c3 & 63));
                i += 3;
            }

        }

        return string;
    }

}


function printClick() {
  var w = window.open();
  var html = "<?php echo $emailheader; ?>";
  var html2 = "<?php echo $emailbody; ?>";


  var decodedString = Base64.decode(html);
  var decodedString2 = Base64.decode(html2);


$(w.document.head).html(decodedString);
$(w.document.body).html(decodedString2);
}

</script>
