Javascript If-else [英] Javascript If-else

问题描述

尝试使用/或其他方式执行我的第一个Javascript操作。基本上我想根据从收音机框字段中选择的数字显示DIV。如果选择了选项3，我希望div 1,2和3可见。
我显然在某个地方出错了。
非常感谢思考/帮助。

Attempting to do my first bit of Javascript if / else. Basically I would like to display DIVs according to the number selected from the Radio box field. If option 3 is selected, I would like div 1, 2 and 3 to be visible. I am clearly going wrong somewhere. Thoughts / help is very much appreciated.

<script type="text/javascript" >

$(document).ready(function() {

$("input[name$='supplier']").click(function() {

var test = $(this).val();

if (test=1)
{
$("div.hidesupplier").hide();
$("#suppliersourced1").show();
}

else if (test=2)
{
$("div.hidesupplier").hide();
$("#suppliersourced1").show();
$("#suppliersourced2").show();
}

else if (test==3)
{
$("#suppliersourced1").show();
$("#suppliersourced2").show();
$("#suppliersourced3").show();
}

});
});
</script>

Number of Suppliers:
<label><input name="supplier" type="radio" value="1">1.</label> 
<label><input name="supplier" type="radio" value="2">2.</label>
<label><input name="supplier" type="radio" value="3">3.</label>

<div id="suppliersourced1" class="CF hidesupplier" style="display: none;">Supplier One</div>
<div id="suppliersourced2" class="CF hidesupplier" style="display: none;">Supplier Two</div>
<div id="suppliersourced3" class="CF hidesupplier" style="display: none;">Supplier Three</div>

推荐答案

在前2个中你有=而不是==条件。

You have = instead of == in your first 2 conditions.
