Firefox的JavaScript问题设置变量 [英] Firefox javascript problem setting variable
问题描述
我已经做了一个小小的JavaScript脚本，设置一个值（在这里命名股票），我想在下拉列表中使最大值。如果它大于6，它将是最大值。
这里是代码：
< script type =text / javascript>
函数selecteazaElement（id，stock）
{
document.addtobasket.idOfSelectedItem.value = id;
var number23 = document.addtobasket.number;
number23.options.length = 0;
if（stock> = 6）
stock = 6;
for（i = 1; i <= stock; i ++）
{
// alert（'id：'+ id +'; stock：'+ stock）;
number23.options [number.options.length] = new Option（i，i）;
}
//window.status=\"my status;
}
< / script>
我使用这种形式的代码：
< form =addtobasketname =addtobasketmethod =POSTaction =<？= Route :: url（'Add to Basket' sale_id'=> $ sale-> id））;？>>
< input type =hiddenname =idOfSelectedItemid =idOfSelectedItemvalue = - 1>
< option value = 0>选择产品数量< / option> < /选择>
< button type =submitname =submitonclick =valbutton（addtobasket）;> Adauga in cos< / button>< br />
< / fieldset>
< / form>因此，在用户选择一个产品后，形成一个列表，他也可以选择一个（产品）数量，
我的问题是：
它在Chrome和Opera中完美工作，但不会在Firefox的下拉列表中显示数字。我不知道为什么呢？
谢谢！
解决方案在Firefox中导致这个问题：
number23.options [number.options.length] = new Option（i，i） ;
更改为：
number23.options [number23.options.length] = new Option（i，i）;
，它就会起作用。

i have made a little javascript script that sets a value (named here stock), which i want to make maximum in a drop down list. it will be the maximum value if it is greater that 6.
Here is the code:
<script type="text/javascript">
function selecteazaElement(id,stock)
{
document.addtobasket.idOfSelectedItem.value=id;
var number23=document.addtobasket.number;
number23.options.length=0;
if (stock>=6)
stock=6;
for (i=1;i<=stock;i++)
{
//alert ('id: '+id+'; stock: '+stock);
number23.options[number.options.length]=new Option(i, i);
}
//window.status="my status";
}
</script>
i use this code in this form:
<form id="addtobasket" name="addtobasket" method="POST" action="<?= Route::url('Add to Basket', array('sale_id' => $sale->id)); ?>">
<input type="hidden" name="idOfSelectedItem" id="idOfSelectedItem" value="-1">
<select name="number" id="number">
<option value=0>Choose the number of products</option> </select>
<button type="submit" name = "submit" onclick="valbutton(addtobasket");>Adauga in cos</button><br />
</fieldset>
</form>
So after the user chooses a product,form a list he can also choose a number(of products)
my problem is:
It works perfectly in chrome and opera, but doesn't display the numbers in the drop down list in Firefox. i wonder why is that?
Thank you!
解决方案 This line is causing the problem in Firefox:
number23.options[number.options.length]=new Option(i, i);
Change it to:
number23.options[number23.options.length]=new Option(i, i);
and it will work.
