Question

尝试在管理页面上进行ColdFusion编辑和删除部分。可以选中复选框，然后编辑或删除所选用户。

以下是代码。

<td>
    <input type = "text" name = "firstname" value = "#firstname#">
    <input type = "text" name = "lastname" value = "#lastname#">
    <input type = "text" name = "email" value = "#email#">
    <input type = "text" name = "user_name" value = "#user_name#">
    <input type = "text" name = "password" value = "#password#">
</td>
<td width="120">

    <input type="checkbox" name="Edit" value="Edit"> Edit <br>

    <input type="checkbox" name="Delete" value="#ID#"> Delete <br>
    <input type="submit" name="submit" value="Submit Changes" id = "Submit">

<!-- Action Page-->
<cfif isDefined("FORM.Delete") AND #Form.Delete# NEQ "">
<cfquery datasource = "feic_test">
    DELETE FROM UserLogin
    WHERE username = <cfqueryparam value = "#FORM.username#"
                            cfsqltype = "cf_sql_varchar">
</cfquery>
</cfif>

代码尚未完成，但到目前为止我还没有。如何让它有两个复选框，一个用于编辑，一个用于删除，然后一旦单击提交按钮，就会采取行动编辑数据库上的用户名或删除它？

Answer 1

<input type="radio" name="action" value="Edit"> Edit <br>
<input type="radio" name="action" value="Delete"> Delete <br>
<input type="submit" name="submit" value="Submit Changes" id = "Submit">

<!-- Action Page-->
<cfif isDefined("FORM.action") AND #Form.action# eq "Delete">
<cfquery datasource = "feic_test">
    DELETE FROM UserLogin
    WHERE username = <cfqueryparam value = "#FORM.username#"
                            cfsqltype = "cf_sql_varchar">
</cfquery>
<cfelseif isDefined("FORM.action") AND #Form.action# eq "Edit">
<!--- Edit code --->
</cfif>

Answer 2

假设#username＃是主键

目前，当您检查编辑时，您并没有推翻＃ID＃。我假设#ID是

您可能希望使用

等表单字段

var prev = -1;

function bubbles(bi){
   if (bi != prev){
//           put the rest of your bubbles(bi) code put here
   }
   prev = bi;
}
