关于“筑巢”的问题使用Javascript [英] Question on "nesting" Javascript
问题描述
大家好。
我试图让这个页面工作使用
< script src =" url / test.php?webid = ADSasdfasdwerqy34"> //你明白我的意思
在test.php我这样做:
var test =''hello world。'' ;
document.write(测试);
当然这当我调用第一页时有效,它实际显示:你好
世界。
但我现在想要一些与众不同的东西。我想要一个提醒。
var test ="< SCRIPT>
window.alert(''hello world'');
< / SCRIPT" ;;
document.write(test);
这绝对没有。你能帮我吗?我需要这个工作!
Thx
米歇尔

替换上面只是:
window.alert(" hello world");

我会假设你有一些理由要添加一个新的脚本元素
而不仅仅是它当前的内容。
我在上面看到两个错误。
首先,Javascript字符串文字不能包含换行符。
更改为:
var test ="< SCRIPT> \ n" +
" window.alert(''hello world''); \ n" +
" < / SCRIPT";
如果你想要的字符串与你想要的完全相同。
其次,你错过了一个 ;>"在< / SCRIPT之后。
如果上述代码包含在HTML页面中的
脚本元素中,则可能会出现第三个潜在错误,因为内容
首次出现< /时结束了这样的结果。因此,总的来说,将行更改为:
var test ="< SCRIPT> \ n" +
" window.alert(''hello world''); \ n" +
" < \ / SCRIPT>" ;;

你好世界。

将以上内容替换为:
window.alert(" hello world");
你这么好笑。
任何人都更认真?
Hi everyone.
I am trying to get this page to work using
<script src="url/test.php?webid=ADSasdfasdwerqy34"> //you get my point
in test.php I do something like this:
var test=''hello world.'';
document.write(test);
of course this works when I call the first page, it actually displays: hello
world.
But I now want something different. I want an alert coming up.
var test="<SCRIPT>
window.alert(''hello world'');
</SCRIPT";
document.write(test);
This does absolutely nothing. Can you help me please? I need this to work!
Thx
Michel

replace above with just:
window.alert("hello world");

I''ll assume you have some reason for adding a new script element
instead of just its content to the current one.
I see two errors in the above.
First of all, a Javascript string literal cannot contain newlines.
Change it to:
var test="<SCRIPT>\n"+
" window.alert(''hello world'');\n"+
" </SCRIPT";
if you want exactly the same string as you seem to intend.
Second, you are missing an ">" after the "</SCRIPT".
A third potential error can occour if the above code is contained in a
script element in an HTML page, since the content of such ends at the
first occurence of "</". So, in total, change the line to:
var test="<SCRIPT>\n"+
" window.alert(''hello world'');\n"+
" <\/SCRIPT>";
