多个文本框有帮助 [英] Multiple Text Boxes help
问题描述
我需要编写一个表单，要求用户定义问题的数量（这只是从下拉菜单中），根据他们选择的数字，他们将被要求在单独的文本框中定义每个问题（每个问题的一个文本框）。因此，如果他们选择2作为问题的数量，他们将被给予两个文本框，5个框用于从下拉列表中选择5。
我想我需要一些javascript（用于表单验证），一些用于表单邮件的PHP，但它是动态文本框我完全失去了。
有人能指出我正确的方向吗？
但它是动态文本框我完全失去了。
i为此目的推荐javascript和DHTML
你应该在你的HTML中有类似的东西 - < div id =''textboxes' '>< / div>
带有数字的下拉列表可以调用我在下面为你写的函数
展开 | 选择 | Wrap | 行号
我试过这个;
< html>
< head>
< / head>
< body>
< select名称= QUOT;盒" onChange =" boxes（）">
< option value ="">选择< / option>
< option value =" 1"> 1< / option>
< option value =" 2"> 2< / option>
< / select>
< script type =" text / javascript">
功能框（NumberOfBoxes）{
for（i = 0; i< NumberOfBoxes; i ++ ）{
box + ="< textarea name =''textbox [NumberOfBoxes]''>< / textarea>" ;;
}
document.getElementById（''textboxes''）。innerHTML = boxes;
}
< / script>
< div id =''textboxes''>
盒子应该到这里
< / div>
< / body>
< / html>
它只提供一个带有大量脚本的文本框:-(
想想我明天再去上班。
< selec t name =" boxes" onChange =" boxes（）">
//盒子需要一个参数number文本框
//你需要将选项值传递给它，例如盒子（2）;
//你可以试试这个盒子（this.value）; - 我不确定这是否有效
//但你需要以某种方式传递一个值
问候

I need to write a form that asks the usser to define the number of problems (this is simply from a dropdown menu), depending on the number they select they will be asked for a definition of each problem in a seperate text box (one text box for each problem). So if they pick 2 as the number of problem they will be given two text boxes, 5 boxes for selecting 5 from the drop down list.
I think I need some javascript (for form validation), some php for the form-mailer, but it''s the dynamic text boxes I''m at a total loss at.
Can anyone point me in anything like the right direction?解决方案but it''s the dynamic text boxes I''m at a total loss at.i recomend javascript and DHTML for that purpose
you should have something like that in your HTML - <div id=''textboxes''></div>
drop down list with a numbers can call a function i wrote for you below
Expand|Select|Wrap|Line Numbers
I tried this;
<html>
<head>
</head>
<body>
<select name="boxes" onChange="boxes()">
<option value="">choose</option>
<option value="1">1</option>
<option value="2">2</option>
</select>
<script type="text/javascript">
function boxes(NumberOfBoxes){
for(i=0;i<NumberOfBoxes;i++){
boxes += "<textarea name=''textbox[NumberOfBoxes]''></textarea>";
}
document.getElementById(''textboxes'').innerHTML = boxes;
}
</script>
<div id=''textboxes''>
boxes should go here
</div>
</body>
</html>
and it give only one text box with loads of script showing :-(
Think I''ll have another go at work tomorrow.
<select name="boxes" onChange="boxes()">
// boxes need one parameter "number" of textboxes
// u need to pass option value to it, e.g. boxes(2);
// u might try this boxes(this.value); - i''m not sure if that will work
// but u need to pass a value somehow
