The example in this article describes the implementation method of JS pop-up dialog box. Share it with everyone for your reference, the details are as follows:
1. Warning box
<html> <head> <script type="text/javascript"> function disp_alert() { alert("我是警告框!!") } </script> </head> <body> <input type="button" onclick="disp_alert()" value="显示警告框" /> </body> </html>
2. Confirm the cancel box
<html> <head> <script type="text/javascript"> function disp_confirm() { var r=confirm("按下按钮") if (r==true) { document.write("您按了确认!") } else { document.write("您按了取消!") } } </script> </head> <body> <input type="button" onclick="disp_confirm()" value="显示确认框" /> </body> </html>
3. There is an input box
<html> <head> <script type="text/javascript"> function disp_prompt() { var name=prompt("请输入您的名字","Bill Gates") if (name!=null && name!="") { document.write("你好!" + name + " 今天过得怎么样?") } } </script> </head> <body> <input type="button" onclick="disp_prompt()" value="显示提示框" /> </body> </html>
I hope this article will be helpful to everyone in JavaScript programming.
