使用条形码阅读器防止chrome中的打开下载窗口 [英] Prevent open downloads window in chrome with barcode reader

问题描述

我的网站（MVC3，C＃）和条形码阅读器存在此问题。
在我的表格中我有这样的内容：

 < ajax form ....> 
 
< input type = text /> 
 
< div id = list> 
< / div> 
 
< / form> 
  

输入用条形码阅读器填充并自动提交带有ajax的表单，填写div使用id = list。
我的问题是，使用chrome和ie，在文本被提交后，下载窗口出现在chrome中，收藏夹窗口出现在ie中。我想这是因为条形码阅读器在文本中加入[CR] [LF]并打开那些窗口。我认为条形码阅读器在某个时刻插入了一个ctrl-j，因为该组合打开了chrome中的下载窗口和ie中的收藏夹，但是使用firefox下载窗口没有打开（也是ctrl-j）。

我不想告诉我的客户配置条形码阅读器以便我的页面正常工作，所以我想在javascript中使用sollution来解决这个问题。

谢谢!!!

解决方案

我找到了这个链接，但唯一的解决方案是更改扫描仪的默认字符...我不确定我可以改变我的虽然如此，像你一样，我也在寻找与浏览器相关的修复工具......也许是javascript。我将尝试使用javascript处理字符以防止发生这种情况...如果我有任何成功，我会尝试并记得回到这里并告诉你hehehehehe

我认为这解决了这个问题......

  $（文件）.ready（function（）{
 $（＃input）。keydown（function（e）{
 if（e.which == 17 || e.which == 74）{
 e.preventDefault（）; 
} else {
 console.log（e.which）; 
} 
}）
}）; 
  

lemme知道他的作品是否也适合你...确保你也清空了缓存...... / p>

i have this problem with my website (MVC3, C#) and a barcode reader. In my form i have something like this:

<ajax form....>

<input type=text />

<div id=list>
</div>

</form>

And the input is filled with a barcode reader and automatically submits the form that with ajax, fills the div with the id = list. My problem is that with chrome and ie, after the text is submited, a downloads windows appears in chrome and the favorites window appears in ie. I suppose that is because the barcode reader insers a [CR][LF] in the text and that opens those windows. I thought that the barcode reader was inserting a ctrl-j in some moment because that combination opens the downloads window in chrome and the favorites in ie, but with firefox the downloads window doesnt open (and is also ctrl-j).

I dont want to tell my client to configure the barcode reader so my page works, so i want a sollution in javascript maybe that fixes that problem.

thanks!!!

解决方案

i found this link but the only solution was to change your scanner's default character... i'm not sure I can change mine though so , like you, I'd be looking for a browser-related fix too.. maybe javascript. i'll try handling the characters with javascript to prevent that from happening... if I have any success i'll try and remember to come back here and tell you hehehehehe

i think this solves the issue....

$(document).ready(function(){
    $("#input").keydown(function(e){
        if(e.which==17 || e.which==74){
            e.preventDefault();
        }else{
            console.log(e.which);
        }
    })
});

lemme know whether his works for you too.. make sure you empty the cache too...
