我正在尝试从select元素设置输入框的值和文本。
var p = document.getElementById("pretestNameSelect");
var test = p.options[p.selectedIndex].value;
if (choice.toString() == "type0")
{
alert(test);
$(document.getElementById("type0")).show();
hideOtherQuestionDivs(choice.toString());
$(document.getElementById("pretestNameSelectHiddenTextQ0")).value = "test";
$(document.getElementById("pretestNameSelectHiddenTextQ0")).text = "test";
alert(document.getElementById("pretestNameSelectHiddenTextQ0").value);
}
警报(测试)工作并显示正确的值,但未设置值,警报(doc ...)显示空警报。
可能是什么问题?

您正在将Jquery选择器与DOM选择器混合使用。
您可以使用
library(arules)
data("Adult")
rules <- apriori(Adult, parameter = list(supp = 0.5, conf = 0.9, minlen = 2))
item <- "race=White"
rules.sub <- subset(rules, lhs %in% item & size(lhs)==1)
inspect(rules.sub)
# lhs rhs support confidence lift
# 7 {race=White} => {native-country=United-States} 0.7881127 0.9217231 1.0270761
# 8 {race=White} => {capital-gain=None} 0.7817862 0.9143240 0.9966616
# 9 {race=White} => {capital-loss=None} 0.8136849 0.9516307 0.9982720
或
$('#pretestNameSelectHiddenTextQ0').val(test);
