本文实例讲述了jquery复选框多选赋值给文本框的方法。分享给大家供大家参考。具体实现方法如下:
<!DOCTYPE html>
<html xmlns=\"http://www.w3.org/1999/xhtml\">
<head>
<title>jquery点击复选框触发事件给input赋值</title><base target=\"_blank\" />
<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />
<style type=\"text/css\">
* {
margin: 0;
padding: 0;
list-style-type: none;
}
a, img {
border: 0;
text-decoration: none;
}
body {
font: 12px/180% Arial, Helvetica, sans-serif, \"新宋体\";
}
table {
empty-cells: show;
border-collapse: collapse;
border-spacing: 0;
}
/* tablist */
.tablist {
width: 400px;
border: solid 8px #ddd;
margin: 40px auto;
}
.tablist td {
line-height: 24px;
border-bottom: solid 1px #ddd;
text-align: left;
padding: 10px;
}
.tablist td input {
line-height: 20px;
margin-left: 5px;
}
.tablist td .txtValue
{
padding: 3px 0;
width: 180px;
}
</style>
</head>
<body>
<table cellpadding=\"0\" cellspacing=\"0\" class=\"tablist\">
<tr>
<td><input class=\"txtValue\" type=\"text\" name=\"keleyi\" value=\"\" /> <input type=\"checkbox\" data-type=\"checkall\" />全选</td>
</tr>
<tr>
<td>
<input type=\"checkbox\" name=\"keleyi\" data-type=\"checkbox\" data-value=\"张三\" value=\"1\" />张三
<input type=\"checkbox\" name=\"keleyi\" data-type=\"checkbox\" data-value=\"李四\" value=\"2\" />李四
<input type=\"checkbox\" name=\"keleyi\" data-type=\"checkbox\" data-value=\"赵五\" value=\"3\" />赵五
<input type=\"checkbox\" name=\"keleyi\" data-type=\"checkbox\" data-value=\"王六\" value=\"4\" />王六
</td>
</tr>
</table>
<script type=\"text/javascript\" src=\"jquery/jquery-1.11.2.min.js\"></script>
<script type=\"text/javascript\">
$(function(){
$(\'[data-type=\"checkbox\"]\').click(function(){
var data_value = $(this).attr(\'data-value\'),
txtalso = $.trim($(\".txtValue\").val());
if($(this).prop(\"checked\")) {
if(txtalso.length > 0) {
if(txtalso.indexOf(data_value+\',\') != -1) {
return ;
} else {
txtalso += data_value + \',\';
}
} else {
txtalso = data_value+\',\';
}
} else {
if(txtalso.indexOf(data_value+\',\') != -1) {
txtalso = txtalso.replace(data_value+\',\', \'\');
}
}
$(\".txtValue\").val(txtalso);
});
$(\'[data-type=\"checkall\"]\').click(function(){
var str = \'\';
if($(this).prop(\"checked\")) {
$.each($(\'[data-type=\"checkbox\"]\'), function(i){
str += $(this).attr(\'data-value\') + \',\';
});
$(\'[data-type=\"checkbox\"]\').prop(\'checked\', true);
} else {
$(\'[data-type=\"checkbox\"]\').prop(\'checked\', false);
}
$(\".txtValue\").val(str);
});
});
</script>
</body>
</html>
希望本文所述对大家的jQuery程序设计有所帮助。
