jquery 对特俗的几个标签的取值

select 标签

var draftType = $("#contentType1").val(); //被选中option的value

var draftType = $("#contentType1").find("option:selected").text(); //被选中option的text

$("#contentType1").val(selectValue);//对select实现赋值

input file

input:file enctype="multipart/form-data" //form表单提交

ajaxPost:false //异步提交

var file1 = $("#uploadFileItem").val(); //上传文件的路径

var index1 = file1.lastIndexOf(".");

var index2 = file1.length;

var postf = file1.substring(index1,index2);//文件后缀名

input:radio

<input
type="radio"id="radios1"
name="radios"value="190110"/> 内刊

<input
type="radio"id="radios2"
name="radios"value="190120"/> 外刊

//绑定添加事件
$(":radio").click(function(){
//取值
var maganizeAttr = $('input:radio[name="radios"]:checked').val();
if(maganizeAttr==190110){
$("#bookNumSpan").hide();//div隐藏
}else{
$("#bookNumSpan").show();//div显示
}
});

input:checkbox

//全选或全不选

function selectAll(){
varobj1=document.getElementById("allSelect1");
var obj =document.getElementsByName("maganizeTypes");
if(obj1.checked ==
true){
for(var i=0; i
< obj.length; i++){
obj[i].checked= true;

}
}else{
for(var i=0; i
< obj.length; i++){
obj[i].checked= false;

}
}
}
