如果我有这样的代码,有引号和作者,我怎样才能得到两个input type="text"
框,我可以写两个名称,然后将名称显示在引号中代替“(随机用户) )“?
//store the quotations in arrays
quotes = [];
authors = [];
quotes[0] = "(randomuser) example (randomuser) example?";
authors[0] = "Authors!";
quotes[1] = "(random user) example (random user) example?";
authors[1] = "Authors!";
//calculate a random index
index = Math.floor(Math.random() * quotes.length);
//display the quotation
document.write("<DL>\n");
document.write("<DT>" + "\"" + quotes[index] + "\"\n");
document.write("<DD>" + " " + authors[index] + "\n");
document.write("</DL>\n");
//done
答案 0 :(得分:0)
我认为您想要使用从几个<input>
标记获得的字符串替换quotes数组中的(randomuser)。在这种情况下,您可以获得这些输入的内容,如下所示:
var user1 = document.getElementById("input1").value;
var user2 = document.getElementById("input2").value;
现在,您可以使用String.replace()
替换“(randomuser1)”和“(randomuser2)”这些输入值,如下所示:
//Sub in the usernames
var newquote = quotes[0].replace("(randomuser1)", user1); //quotes[0] can of course be any index
newquote = newquote.replace("(randomuser2)", user2);
然后你可以显示newquote
。请注意,您应该避免使用document.write()
。相反,您可以在页面上创建一个显示div,然后将引号放入其中,如下所示:
var quotediv = document.getElementById("quoteDiv"); //get the div (or any other element) that you want to display the quote in
quotediv.innerHTML = newquote; //display your quote in the div.
修改强>:
要从较大的列表中随机选择引用,您可以将quotes[0]
更改为quotes[Math.floor(Math.random() * quotes.length)]
之类的内容。要添加更多用户,您需要添加更多输入和更多替换语句。例如:
//Sub in the usernames
var ind = Math.floor(Math.random() * quotes.length); //select random quote
var newquote = quotes[ind].replace("(randomuser1)", user1);
newquote = newquote.replace("(randomuser2)", user2);
newquote = newquote.replace("(randomuser3)", user3);
newquote = newquote.replace("(randomuser4)", user4);
newquote = newquote.replace("(randomuser5)", user5);
对于大量用户来说,这可以简化为for循环,但我会让你弄清楚。
