Safari/JQUery-在页面上插入和更新隐藏字段

问题描述

在野生动物园中，我试图向DOM中插入隐藏"字段，然后按如下所示更新其值.

In safari, Im trying to insert a Hidden field into the DOM then update its value as below.

colHiddenFieldId = 'row_100000_0_NewValue'  

$("#" + colHiddenFieldId).val('TEST')

但是永远不会设置该值，看起来Safari并不认为隐藏字段存在.我知道是因为它可以在人类已知的所有其他浏览器上使用！！

However the value is never getting set, it looks Safari dosn't think the hidden field exists. I know it does because it works on every other browser known to man!!!

这在狩猎之旅书中是一件坏事吗?

Is this a bad thing to do in safaris book?

推荐答案

您是否肯定您的名字中没有遗漏"0"，或者添加了太多?您可以通过循环浏览所有隐藏字段并提醒其ID来查看Safari是否有权访问它:

Are you positive you're not missing a '0' in the name, or maybe adding too many? You can see if Safari has access to it by cycling through all hidden fields and alerting their ID:

$("input[type='hidden']").each(function(){
  alert($(this).attr("id"));
});

创建字段...

var myId = "someIdHere";
$("<input />")
  .attr("type","hidden")
  .attr("id",myId)
  .val("Something")
  .appendTo("body");
