当我点击add-more时,它会添加新行(可能有很多行,我没有包含javascript,这里我用两个输入行硬编码了表单),有两个字段和十字图标要删除那个领域。 并删除该字段我有一个javascript函数
$(document).on('click','a.remove-operator-code',function() {
$(this).parents('tr').first().remove();
});
它已成功删除该行,但我不知道焦点的位置,我想解决这个焦点问题,当我们删除特定行时,焦点必须转到前一行的第一个输入字段

您需要使用:
$(document).on('click','a.remove-operator-code',function() {
vat prevtr = $(this).closest('tr').prev();
if(prevtr.length)
prevtr.find('input:first').focus()
$(this).closest('tr').remove();
});

这会对你有帮助..
演示:http://jsfiddle.net/ajnf988s/
$(document).on('click','a.remove-operator-code',function() {
$(this).parents('tr').prev('tr').find('input[type=text]:first').focus();
$(this).parents('tr').remove();
});
