使用 jQuery 在 SELECT 框中选择带有引号的项目时遇到问题
我有一个带有列表的隐藏表单，当用户想要查看此表单时，我需要从中选择一个选项。 我正在使用 var 受让人 = '人员姓名';
jQuery('#edit-form' option[value='+option+']:first').attr("已选择", "已选择");
我尝试这样做，但这不起作用，因为选项标记中的值也没有用 \ 指定，所以它找不到匹配项
jQuery('#edit-form option[value='+option.replace(/\'/,'\\\'')+']:first').attr("selected", "selected");
那么这样做是我唯一的选择吗？
jQuery('#edit-form option').each(function(){
if(jQuery(this).val() == option) {
jQuery(this).attr("selected", "selected");
return false;
}
});

I am having a hidden form with a list which I need to select an option from when a user wants to view this form.
I was using
var assignee = 'persons name';
jQuery('#edit-form' option[value='+option+']:first').attr("selected", "selected");
I tried doing this, but this is not working as the value in the option tag is not specified with the \ as well, so it won't find a match
jQuery('#edit-form option[value='+option.replace(/\'/,'\\\'')+']:first').attr("selected", "selected");
So is doing it this way the following my only option ?
jQuery('#edit-form option').each(function(){
if(jQuery(this).val() == option) {
jQuery(this).attr("selected", "selected");
return false;
}
});

怎么样：
请注意
"和'字符的使用。例如，这些都是有效字符串：
但不是这些。
您还可以使用语法荧光笔查看这一点。
编辑：
如果我使用这个对我有用：
注意：我使用
.first()而不是:first和正确的select[name=" select3"]。确保使用正确的 jQuery 选择器。What about:
Note the use of the
"and'characters.E.g. These are all valid strings:
but not these
You can also see this with the syntax highlighter.
Edit:
Works for me if I use this:
Note: I use
.first()instead of:firstand properselect[name="select3"]. Make sure that you use proper jQuery selectors.
