html代码:
1234567891011121314151617181920 | < tbody id = "history_income_list" > < tr > < td align = "center" >< input type = "text" class = "input-s input-w input-hs" ></ td > < td align = "center" >< input type = "text" class = "input-s input-w input-hs" ></ td > < td align = "center" >< input type = "text" class = "input-s input-w input-hs" ></ td > < td align = "center" >< a class = "" onclick = "history_income_del(this);" href = "###" >删除</ a ></ td > </ tr > < tr > < td align = "center" >< input type = "text" class = "input-s input-w input-hs" ></ td > < td align = "center" >< input type = "text" class = "input-s input-w input-hs" ></ td > < td align = "center" >< input type = "text" class = "input-s input-w input-hs" ></ td > < td align = "center" >< a class = "" href = "###" >删除</ a ></ td > </ tr > < tr > < td align = "center" >< input type = "text" class = "input-s input-w input-hs" ></ td > < td align = "center" >< input type = "text" class = "input-s input-w input-hs" ></ td > < td align = "center" >< input type = "text" class = "input-s input-w input-hs" ></ td > < td align = "center" >< a class = "" href = "###" >删除</ a ></ td > </ tr > </ tbody > |
方法一:
1234567891011 | var trList = $( "#history_income_list" ).children( "tr" )
for ( var i=0;i<trList.length;i++) {
var tdArr = trList.eq(i).find( "td" );
var history_income_type = tdArr.eq(0).find( "input" ).val(); //收入类别
var history_income_money = tdArr.eq(1).find( "input" ).val(); //收入金额
var history_income_remark = tdArr.eq(2).find( "input" ).val(); // 备注
alert(history_income_type);
alert(history_income_money);
alert(history_income_remark);
} |
方法二:
123456789101112 | $( "#history_income_list" ).find( "tr" ).each( function (){
var tdArr = $( this ).children();
var history_income_type = tdArr.eq(0).find( "input" ).val(); //收入类别
var history_income_money = tdArr.eq(1).find( "input" ).val(); //收入金额
var history_income_remark = tdArr.eq(2).find( "input" ).val(); // 备注
alert(history_income_type);
alert(history_income_money);
alert(history_income_remark);
}); |
