我有以下代码来隐藏/显示元素,具体取决于在SharePoint Server表单上的下拉列表中选择的值。根据jQuery下拉列表中选择的内容验证不同的字段?
它工作正常,但我想添加一些验证(必填字段),具体取决于下拉列表“级别”中选择的内容。
Sharepoint有一个名为PreSaveItem()的默认函数,我必须调用它才不提交页面。
<script type="text/javascript">
//Items to hide when page first loads
$(document).ready(function ($) {
$('nobr:contains("Vision")').closest('tr').show();
$('nobr:contains("Goal")').closest('tr').show();
$('nobr:contains("Performance")').closest('tr').hide();
$('nobr:contains("Start Date")').closest('tr').show();
$('nobr:contains("Target Date")').closest('tr').show();
});
</script>
<script type="text/javascript">
$(document).ready(function ($) {
$("select").bind("change", function(e){
var thistag = e.target.title;
var thisvalue =e.target.value;
if (thistag == "Level")
{
if (thisvalue == "Vision")
{
$('nobr:contains("Vision")').closest('tr').hide();
$('nobr:contains("Goal")').closest('tr').hide();
$('nobr:contains("Performance")').closest('tr').hide();
$('nobr:contains("Start Date")').closest('tr').hide();
$('nobr:contains("Target Date")').closest('tr').hide();
};
if (thisvalue == "Goal")
{
$('nobr:contains("Vision")').closest('tr').show();
$('nobr:contains("Priority")').closest('tr').show();
$('nobr:contains("Goal")').closest('tr').show();
$('nobr:contains("Performance")').closest('tr').hide();
$('nobr:contains("Start Date")').closest('tr').show();
$('nobr:contains("Target Date")').closest('tr').show();
};
if (thisvalue == "Performance")
{
$('nobr:contains("Vision")').closest('tr').show();
$('nobr:contains("Goal")').closest('tr').show();
$('nobr:contains("Performance")').closest('tr').hide();
$('nobr:contains("Start Date")').closest('tr').hide();
$('nobr:contains("Target Date")').closest('tr').hide();
};
if (thisvalue == "Actions")
{
$('nobr:contains("Vision")').closest('tr').show();
$('nobr:contains("Goal")').closest('tr').show();
$('nobr:contains("Performance")').closest('tr').hide();
$('nobr:contains("Start Date")').closest('tr').show();
$('nobr:contains("Target Date")').closest('tr').show();
};
};
});
});
</script>
<script type="text/javascript">
$(document).ready(function ($) {
$().SPServices.SPCascadeDropdowns({
relationshipList: "Priority Tracking List",
relationshipListParentColumn: "FoundationName",
relationshipListChildColumn: "Title",
parentColumn: "Vision",
childColumn: "Goal"
});
});
</script>
我的代码来验证是(我把它的第一个脚本内上方):
//bind a change event to all controls to validate
$("input[title=Target Date],input[title=Start Date],select[title=Vision],select[title=Goal]").change(function(){
checkControls()
});
//the change event function - check the status of each control
function checkControls(){
//set a variable to count the number of valid controls
var controlsPassed = 0;
//set up a selector to pick .each() of the target controls
$("input[title=Target Date],input[title=Start Date],select[title=Vision],select[title=Goal]").each(function(){
//if the control value is not zero AND is not zero-length
if($(this).val() != 0 && $(this).val().length != 0) {
//add one to the counter
controlsPassed += 1
}
});
//call the showHide function and pass the true/false statement of 4 valid controls
return (controlsPassed == 4);
}
function PreSaveItem() {
return checkControls()
}
如果控件验证是空的,当我点击后页面加载没有任何反应提交。 但是,根据在下拉列表中选择什么“级别”,我想检查要验证的不同项目,如何修改这些脚本以实现此目的?
谢谢,那很容易:) – Peter 2010-08-16 02:32:29
