以下一段 JavaScript 有什么问题

Question

I am creating iframe in which user can set height (stored in setHeight variable) by entering input but I am struck at following and failed to find solution.

document.write("<iframe src=\"" + decodeURIComponent(finalSearch) + "\" width=\"100\%\" height="setHeight">");

Please Help!

Answer 1

You're not concatenating the variable setHeight into your string, and you're not escaping all of your double quotes. Try this:

document.write("<iframe src=\"" + decodeURIComponent(finalSearch) + "\" width=\"100\%\" height=\" + setHeight + \">");
