Question

我想获取多个textarea的值并将它们显示为highcharts graph的工具提示。我使用输入和eq选择器来获取多个文本区域的值，但这些值不会作为工具提示返回..

我无法理解错误..小提琴也在这里http://jsfiddle.net/RbenU/8/在这个小提琴文本框已被使用，而我想使用文本区域..

请帮助..

Answer 1

检查小提琴上的样本 http://jsfiddle.net/RbenU/10/

使用textarea作为选择器而不是输入如下

if (serieI == 0) {
      comment = $("textarea:eq(" + (index) + ")").val();
} else {
      //comment = "second serie matched!";
      comment = $("textarea:eq(" + (index1) + ")").val();
}

Answer 2

您可以将input更改为:input：

comment = $(":input:eq(" + (index) + ")").val();
comment = $(":input:eq(" + (index1) + ")").val();
