我正在尝试使用jQuery做一个简单的事情:每当表单加载时,或者如果用户更改选项列表,清除div中一组输入字段的输入字段; 但我有一个时间让选择器工作的魔鬼.
首先,这是我的onclick和onload触发器:
<form name="EditGenotype" action="process_GenotypeMaint.php" method="POST" onsubmit="return false" onload=clear_fetch() >
并在选项列表上:
<SELECT multiple size=6 NAME="marker" onchange=show_marker() onclick=clear_fetch() >
接下来,这是我想要清除的div中的HTML输入元素:
<div class=fetch_results>
<fieldset>
<LEGEND><b>Edit Genotype, call 1</b></LEGEND>
<boldlabel>Allele_1</boldlabel><input id=allele_1_1 name=allele_1_1 size=5 >
<boldlabel>Allele_2</boldlabel><input id=allele_1_2 name=allele_1_2 size=5 >
<boldlabel>Run date</boldlabel><input id=run_date1 name=run_date1 size=10 disabled=true>
</fieldset>
<fieldset>
<LEGEND><b>Edit Genotype, call 2</b></LEGEND>
<boldlabel>Allele_1</boldlabel><input id=allele_2_1 name=allele_2_1 size=5 >
<boldlabel>Allele_2</boldlabel><input id=allele_2_2 name=allele_2_2 size=5 >
<boldlabel>Run date</boldlabel><input id=run_date2 name=run_date2 size=10 disabled=true>
</fieldset>
<fieldset>
<LEGEND><b>Edit Genotype, call 3</b></LEGEND>
<boldlabel>Allele_1</boldlabel><input id=allele_3_1 name=allele_3_1 size=5 >
<boldlabel>Allele_2</boldlabel><input id=allele_3_2 name=allele_3_2 size=5 …我正在通过Michael Hartl的优秀教程,但在尝试使用以下命令准备测试数据库时:bundle exec rake db:test:prepare我收到此错误消息:
错误:必须是数据库sample_app_test的所有者...
这是我在使用开发数据库时从未获得的,因为我为我的Rails应用程序创建了以下数据库角色:
CREATE ROLE demo_app WITH CREATEDB LOGIN
(这是使用Postgresql)
有谁知道为什么这在测试环境中失败了？TIA ...
我是jQuery语法的新手，这可能是一个真正的noobie问题....但是我只是不明白为什么我在加载此页面时会收到错误“ $ .effects is undefined”。如果有人能看到这一点，我将非常有责任... TIA，rixter

这是错误消息:
NoMethodError in UploadsController#create
我的模型的相关部分如下所示:
named_scope :by_name, lambda { |marker_name|
{:conditions => ["marker_name = ?", marker_name]}}
def self.parse_file(file)
FasterCSV.foreach(file.path,:headers=>"first_row", :col_sep=>"\t") do |row|

$markers_arry = [] # define global array for marker names
get_markers(row)
$header_row = 0
# done with header row; loop back to beginning for first row of actual data
next
end
...

这是查询#1:
SELECT count(*)
FROM
dnasample D, ibg_studies ST, subjects S
WHERE
D.studyindex=ST.studyindex
AND ST.studyabrv='CONGER'
AND D.subjectidkey=S.id
AND D.projectindex IS NULL
AND POSITION('Previous subjectid:' in D.comment) IS NULL
返回结果246.
那么这里是查询#2:
SELECT count(*)
FROM
dnasample D, ibg_studies ST, subjects S
WHERE
D.studyindex=ST.studyindex
AND ST.studyabrv='CONGER'
AND D.subjectidkey=S.id
AND D.projectindex IS NULL
AND POSITION('Previous subjectid:' in D.comment)=0
我不明白为什么这些会带来如此不同的结果？
我已经尝试阅读Postgres文档来澄清零和空字符串之间的区别,但还没有太多运气......

这是我想知道的那些日子之一:我是否会失去理智？如果我单步执行这个简单的javascript函数,执行将从第3行跳到第7行.
function editStudy() {
var studyindex = document.StudyMaint.StudyList.selectedIndex;
var studyabrv = document.StudyMaint.StudyList[index].text; //Line 3
var msg="Edit study "+studyabrv+"?";
// Get the Study record id was selected in the picklist,
// then go to Study edit screen, then
if (confirm(msg)) {
location.href="editStudy.php?action=UPDATE&studyindex="+studyindex+"&studyabrv="+studyabrv;
} //Line 7
}
但是我的表格StudyMaint被定义为:
<body>
<?php showUserLine(); ?>
<form name="StudyMaint" action="Process_StudyMaint.php" method="POST" onsubmit="return false">
<div id="dataentrybox">
<div id="innerbox">
<div align="center">

有人看到我在这里做错了吗？
