动态地将Javascript写入新的HTML页面 [英] Dynamically Writting Javascript to a new HTML Page
问题描述
我在下面的代码中使用以下代码尝试通过单击按钮动态地将一些javascript动态写入新的html页面。
I have the following code below in which I am using to attempt to dynamically write some javascript into a new html page at the click of a button.
我是但是在尝试这样做时遇到错误我理论上得到未终止的字符串constamnt
，这应该有效：
I am however getting an error when attempting to do so I get "unterminated string constamnt" in theory, this should work:
var html = '<!DOCTYPE html>\n'
html += '<html>\n'
html += '<head>\n'
html += '<script type="text/javascript">\n'
html += 'function testme() {\n'
html += 'alert("the test worked!")\n'
html += '}\n'
html += '</script>\n'
html += '</head>\n'
html += '<body>\n'
html += '</body>\n'
html += '</html\n'
window.open('','').document.write(html)
推荐答案
你错过了最后一行的收盘>
You are missing a closing > on the last line
html += '</html\n' <-- Missing a greater than
应该是
html += '</html>\n'
如果代码是内联的而不是外部脚本，则需要分解结束脚本标记。
If the code is inline and not in an external script, you will need to break up the closing script tag.
html += '</scr' + + 'ipt>\n';
也可以使用分号。
现在window.open，document.write行看起来很奇怪。大多数开发人员会把它写成
Now the window.open, document.write line looks strange. Most developers would write it as
var winPop = window.open('','');
winPop.document.open();
winPop.document.write(html);
winPop.document.close();
