以前我有一段代码
$(document).bind('keyup', function(e)
{
if (e.keyCode === 13 && $('#domain_name_url').is(':focus'))
{
alert("hii");
$("#submit_replace_button").click();
}
else if(e.keyCode === 13 && $('#search_domain').is(':focus'))
{
//$("#submit_search_button").click();
}
});
曾经工作过。
现在我做了一个简单的更改，因为我想只在keyup事件在表单元素中时才能使用。
所以我把它改成了
$("#m_domain input[type=text]").on('keyup', function(e)
{
if (e.keyCode === 13 && $('#domain_name_url').is(':focus'))
{
alert("hii");
$("#submit_replace_button").click();
}
else if(e.keyCode === 13 && $('#search_domain').is(':focus'))
{
//$("#submit_search_button").click();
}
});
现在它似乎无法正常工作。我做错了什么？
这是我的总html

这是我的JavaScript代码总数。

$("#submit_replace_button").click();

var total_row;
$(this).toggleClass("selected");
var final_class = $(this).attr("class");
var chk_ob = $(this).find("td:first").find("input");
if (final_class.indexOf("selected")>0)
{
$(chk_ob).prop('checked', true);
total_selected_row = t.rows('.selected').data().length;
total_row = t.rows().data().length;
if(total_selected_row == total_row)
{
$("#checkedAll").prop('checked', true);
}
}
else
{
$(chk_ob).prop('checked', false);
$("#checkedAll").prop('checked', false);
}
} );
/* If I comment the below on focus methods, then the total scripts work with keyup method on form.
If I uncomment the below focus methods, then keyup method on form doesn't work, instead it works on `$(document).bind();`
/*
$('#domain_name_url').on('focus',function()
{
$('#submit_search_button').prop("disabled",true);
$('#submit_replace_button').prop("disabled",false);
});
$('#search_domain').on('focus',function()
{
$('#submit_replace_button').prop("disabled",true);
$('#submit_search_button').prop("disabled",false);
});*/
});
但我需要将此提交按钮启用禁用代码。
答案 0 :(得分：1)
这是因为您的2行代码存在冲突
// in the below code you want click event when your domain_name_url
// is focused which will run immediately after focus event
if (e.keyCode === 13 && $('#domain_name_url').is(':focus'))
{
alert("hii");
$("#submit_replace_button").click();
}
当您在#domain_name_url上绑定焦点事件时，它将禁用该按钮。而且您无法点击禁用按钮
$('#domain_name_url').on('focus',function()
{
$('#submit_search_button').prop("disabled",true);
$('#submit_replace_button').prop("disabled",false);
});

我需要放置这样的代码，
$(document).ready(function()
{
$("#domains_list tbody").on( "click", "tr", function ()
{
var total_selected_row;
var total_row;
$(this).toggleClass("selected");
var final_class = $(this).attr("class");
var chk_ob = $(this).find("td:first").find("input");
if (final_class.indexOf("selected")>0)
{
$(chk_ob).prop('checked', true);
total_selected_row = t.rows('.selected').data().length;
total_row = t.rows().data().length;
if(total_selected_row == total_row)
{
$("#checkedAll").prop('checked', true);
}
}
else
{
$(chk_ob).prop('checked', false);
$("#checkedAll").prop('checked', false);
}
} );
/*there are two submit buttons in a single form.
When we press enter, the first submit button submits the form as it works
as a default submit button .
So, we need to place this piece of code to check, which textbox had the focus
when the enter was clicked. If its search textbox, then by default action, submit button1 will act, but if its replace textbox, so submit button 2 is being made clicked.*/
$("#m_domain input[type=text]").on('keyup', function(e)
{
if (e.keyCode === 13 && $('#domain_name_url').is(':focus'))
{
$("#submit_replace_button").click();
}
else if(e.keyCode === 13 && $('#search_domain').is(':focus'))
{
}
});
$('#domain_name_url').on('focus',function()
{
$('#submit_search_button').prop("disabled",true);
$('#submit_replace_button').prop("disabled",false);
});
$('#search_domain').on('focus',function()
{
$('#submit_replace_button').prop("disabled",true);
$('#submit_search_button').prop("disabled",false);
});
});
我是愚蠢的，并没有明白
$("#m_domain input[type=text]").on('keyup', function(e){});
和
$('#domain_name_url').on('focus',function()
{
$('#submit_search_button').prop("disabled",true);
$('#submit_replace_button').prop("disabled",false);
});
$('#search_domain').on('focus',function()
{
$('#submit_replace_button').prop("disabled",true);
$('#submit_search_button').prop("disabled",false);
});
两者都应在$(document).ready(function(){});
