提交按钮操作取决于字段是否与另一个表单匹配 [英] Submit Button Action Depending If Field Matches Another Form
问题描述
我有一页有两种表格，但现在只显示一种。这个想法是，如果消费者从下拉菜单中选择了某个状态，那么当它们点击提交按钮时，它将重定向到感谢页面或第二个表单。
以下是我的表单：
< form action =capture_redirect.phpmethod =post>
< input type =submitid =submitvalue =Check Eligibility>
Javascript：
< script type =text / javascript>
函数提交{
if（document.getElementById（state）='AZ'，'AR'，'CA'）
{
location.href =home.php ;
}
else
{
location.href =capture_redirect.php;
}
}
< / script>
我确定我在这里犯了一个错误，但我似乎无法弄清楚。现在，当消费者点击提交按钮时，它会将他们重定向到感谢页面或回到表单。
我看到了每个单独状态都显示的示例用它自己的if / else语句，但我希望避免这种情况，因为它会使我的文档更长。
1. = == 而不是它。
2.也将你的情况分成三部分，如下图。
3.在您的情况下，您也忘记了'<，大约州 ： -
if（document.getElementById（'state'）。value =='AZ'|| document.getElementById（'状态'）。value =='AR'|| document.getElementById（'state'）。value =='CA'）{.......} else {.....}
或者更有效的方法： -
pre > if（['AZ'，'AR'，'CA']。indexOf（document.getElementById（'state'）。value）） pre>
4.替代 location.href 使用 window.location.href
I have one page with two forms, but only one is shown for now. The idea being is if the consumer selects a certain state from the drop down menu, it will either redirect them to a thank you page or the second form when they click on the submit button.
Here is my form:
<form action="capture_redirect.php" method="post">
<select placeholder="State" name="_State" id="state" required/>
<input type="submit" id="submit" value="Check Eligibility">
Javascript:
<script type="text/javascript">
function submit {
if(document.getElementById(state) = 'AZ', 'AR', 'CA')
{
location.href = "home.php";
}
else
{
location.href = "capture_redirect.php";
}
}
</script>
I'm sure I made an error somewhere here but I can't seem to figure it out. Right now when the consumer clicks on the submit button it either redirects them to the thank you page or back on the form.
I have seen examples where each indivual state is displayed with it's own if/else statements, but I'm hoping to avoid that since it would make my document much longer.
1.= is used for assignment not for comparison so use ==instead of it.
2.Also break your condition into three parts like below.
3.You forgot ''also, around state in your condition:-
if(document.getElementById('state').value == 'AZ' || document.getElementById('state').value == 'AR' || document.getElementById('state').value == 'CA'){.......}else{.....}
Or more efficient way to do it:-
if( ['AZ', 'AR', 'CA'].indexOf( document.getElementById('state').value) )
4.Instead of location.href use window.location.href
