如何提醒其他ASP LISTITEMS [英] How to Alert other ASP LISTITEMS

问题描述

我有以下脚本，每次从下拉菜单中选择语言时我都需要运行警报，当西班牙语被选中时，我能够发出警报（值：es），但我无法运行其他通过添加相同的脚本语言提醒，只有西班牙语会提醒 -





这是脚本：



< asp：DropDownList ID =aicLanguageonchange =dropDownListOnChange（this）; runat =servername =aicLanguageEnabled =True>

< asp：ListItem Value =slText =Select Language>

< asp：ListItem Value =enText =English>

< asp：ListItem Value =mnText =Chinese>

< asp：ListItem Value =jaText =Japanese>

< asp：ListItem Value =ptText =Portuguese>

< asp：ListItem Value =esText =Spanish>

< asp：ListItem Value =deText =German>











< script type ='text / javascript '>



var dropdown = document.getElementById（aicLanguage）;

dropdown.onchange = function（event）{

if（dropdown.value ==es）{

alert（SPANISH SCHEDULE）



}

}





< / script>

I have the following script , I need to run alert each time a language is selected from the dropdown menu , I was able to alert it when spanish is selecte (value: es) , but I was not able to run the other languages alerts by adding the same scripts , only spanish will alert-


Here is the script:

<asp:DropDownList ID="aicLanguage" onchange="dropDownListOnChange(this);" runat="server" name="aicLanguage" Enabled="True">
<asp:ListItem Value="sl" Text="Select Language">
<asp:ListItem Value="en" Text="English">
<asp:ListItem Value="mn" Text="Chinese">
<asp:ListItem Value="ja" Text="Japanese">
<asp:ListItem Value="pt" Text="Portuguese">
<asp:ListItem Value="es" Text="Spanish">
<asp:ListItem Value="de" Text="German">





<script type='text/javascript'>

var dropdown = document.getElementById("aicLanguage");
dropdown.onchange = function (event) {
if (dropdown.value == "es") {
alert(" SPANISH SCHEDULE")

}
}


</script>

推荐答案

使用否则如果

另外请花点时间至少学习编码的基础知识。这是一个浪费你的时间和我们的问题，在你开始尝试编写实际代码之前，对语言的理解是最低限度的。询问每一个小问题都不是一种有效的学习方法。

Use "else if"

Also please take time to at least learn the basics of coding. It's a waste of your time and ours to ask such basic questions as this, a decent understanding of the language in general is a bare minimum before you start trying to write actual code. Asking about every little question is not an efficient way to learn.
