用javascript中的文本菜单替换下拉菜单 [英] replacing a dropdown menu with a text menu in javascript
问题描述
如果有人选择其他选项，我正在尝试用文本字段替换下拉菜单。现在在我的代码中我用它替换了一个段落元素，因为我太懒了，无法找到用于设置文本字段的确切构造函数参数。但是，当选择其他时没有任何反应。
I'm trying to replace a drop down menu I have with a text field if someone chooses the "other" option. Right now in my code I have it replacing it with a paragraph element because I'm too lazy to find the exact constructor arguments for setting up a text field. However, when "other" is selected nothing happens.
有人知道这有什么问题吗？
Does anyone know what's wrong with this?
<html>
<head>
<script type="text/javascript">
function testfunc(arg) {
if(arg.value == "other") {
document.thing.replaceChild(document.test, document.thing.selection)
}
else {
alert("stuff")
}
}
</script>
<body>
<form name="thing">
<select name="selection" onchange="testfunc(document.thing.selection.options[document.thing.selection.selectedIndex])">
<option>yes</option>
<option>no</option>
<option>other</option>
</select>
</form>
<p name="test">lkjsdf</p>
</body>
</html>
推荐答案
这个功能应该是这样的！其他不是其他！它的区分大小写（在linux上无论如何......不确定其他操作系统）否则，谢谢......一直在寻找...很酷的显示/隐藏方式
the function should be like this! Other not other ! its case sensitive (on linux anyway...not sure about other os) Otherwise thanks...been looking for this...cool way of show/hide
<script type="text/javascript">
function show_txt(arg,arg1)
{
if(document.getElementById(arg).value=='Other')
{
document.getElementById(arg1).style.display="block";
document.getElementById(arg).style.display="none";
}
else
{
document.getElementById(arg).style.display="block";
document.getElementById(arg1).style.display="none";
}
}
</script>
