对不起，如果这有点令人困惑，但我会尽力解释我想做的事。
我有一个包含3行和5列的表格。第4列有一个名称-td name =“csl1” - 对于第1行，-td name =“csl2” - 对于第2行，-td name =“csl3” - 对于第3行。第5列有一个名称-td name =“nsl1” - 对于第1行，-td name =“nsl2” - 对于第2行，-td name =“nsl3” - 对于第3行。
我正在尝试使用Jquery遍历名称，以便在单击按钮时获取其值...
$('#purcbutton').click(function(e){
for(i = 1; i <4; i++){
var csl = $("td[name=csl"+i"]").val();
var nsl = $("td[name=nsl"+i"]").val();
var total = parseInt(csl+nsl);
$("td[name=csl"+i"]").val(price);
}
})
问题是这些部分“td [name = csl”+ i“]”似乎是错误的，我显然不允许把'i'放在中间。我对JQuery很新，不知道该怎么做。如果您需要更多信息，请询问。

我认为最好的方法是使用each()功能，这样您就不需要命名tds或trs：
$('#purcbutton').click(function(e){
var csl,nsl,total;
$('tr').each(function(){
csl=$(this).children('td').eq(3).children('input').val(); //the fourth column value
nsl=$(this).children('td').eq(4).children('input').val(); //the fifth column value
total = parseInt(csl+nsl);
$(this).children('td').eq(4).children('input').val(total); //I think you meant "total" by "price" because I don't see any variable called "price"
});
});
答案 1 :(得分：0)
问题出在jquery，＆＃34; 2＆＃34; +＆＃34; 3＆＃34; =＆＃34; 23＆＃34;。
你被接受的结果是5为该parsefloat（＆＃34; 2＆＃34;）+ parsefloat（＆＃34; 3＆＃34;）= 5
$('#purcbutton').click(function(e){
for(i = 1; i <4; i++){
var csl = parseFloat($("td[name=csl"+i"]").text());
var nsl =parseFloat $("td[name=nsl"+i"]").text());
var total =parsecsl+nsl);
$("td[name=csl"+i"]").text(price);
}
})
