我非常需要你的帮助,
变量“x”通常可以使用以下方法设置(默认)
var x = prompt("Please enter your name:","John Smith")
我非常喜欢模仿相同的想法并编写它,以便它可以与我现有的动态/自定义对话框/提示框一起使用。为此,我对异步javascript不是很熟悉,在那个不可能的部门也没有什么经验。
预期结果:
var x = alertBox('Enter your firstname','prompt','John Smith')
这是 HTML/CSS 和 Javascript 标记:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function testit() {
var x = alertBox('Enter your firstname','prompt','John Smith')
alert(x)
}
function alertBox(text, type, ptext) {
var button = '<div id="alertBox_button_div" ><input id="alertBox_button" class="button" style="margin: 7px;" type="button" value="Close" onclick="alertBox_hide()"></div>'
var field = '<div><input id="ptext" class="field" type="text"></div>'
if (type == "err") {
document.getElementById('alertBox_text').innerHTML = text + button
document.getElementById('alertBox_text').style.color = "#FF0000"
document.getElementById('alertBox_text').style.top = "50%"
}
else if (type == "ok") {
document.getElementById('alertBox_text').innerHTML = text + button
document.getElementById('alertBox_text').style.top = "50%"
}
else if (type == "prompt") {
document.getElementById('alertBox_text').innerHTML = text + field + button
document.getElementById('alertBox_text').style.top = "25%"
document.getElementById('alertBox_button').value = "OK"
if (ptext) { document.getElementById('ptext').value = ptext }
}
else {
document.getElementById('alertBox_text').innerHTML = text
}
document.getElementById('alertBox_container').style.visibility = 'visible'
}//end function
function alertBox_hide() {
document.getElementById('alertBox_container').style.visibility = 'hidden'
}
