我有一个表单,当状态为新时,我需要隐藏ETA行,然后为任何其他状态启用它。这就是我尝试的:
var progress, ordered, unordered, completed, cancelled, reg, high, user, trimUser, etaDate, etaRow, etaHour, etaMinutes;
function initiate() {
//declaring necessary variables
declaration()
}
function declaration(){
//Declaration of variables for status changes
sNew = $("option[value='New']");
progress = $("option[value='In Progress']");
ordered = $("option[value='Ordered']");
unordered = $("option[value='Unordered']");
completed = $("option[value='Completed']");
cancelled = $("option[value='Cancelled']");
//Declaring variables for priority changes
reg = $('input[value="ctl00"]');
high = $('input[value="ctl01"]');
//Declaring current user using SPServices
user = $().SPServices.SPGetCurrentUser({
fieldName: "Name",
debug: false
});
//Declaring variables for ETA field manipulation
etaRow = $("nobr").filter(function () { return $.trim(this.childNodes[0].nodeValue) === "ETA"; }).closest("tr");
etaDate = $('input[title="ETA"]');
etaHour = $("[id$=DateTimeFieldDateHours]");
etaMinutes = $("[id$=DateTimeFieldDateMinutes]");
}
function hideETA(){
//hide ETA options
etaRow.hide();
if(sNew.not(:checked)){
alert('CP1');
eta.show();
}
}
所以我尝试的方法是一开始隐藏它(因为新的是默认的),然后当它不是新的时,显示它。
编辑:我想我已经解决了这个问题,这是在@Richard帮助我的if语句和选择器之后我做的:
function setETA(){
//Hide, Display and Disable ETA based on stages
if(sNew.is(":checked")){
etaRow.hide();
}else if (progress.is(":checked")){
//do nothing, should be already showing
}else{
etaDate.attr("readonly","true").css('background-color','#F6F6F6');
etaHour.attr("disabled","disabled");
etaMinutes.attr("disabled","disabled");
}
}
2可能性:
- 显示=无
- 删除选项
对于显示方法:http://jsfiddle.net/r7gLU/1/
// Hide the Option
var opt = $('option[value=New]');
opt.css('display','none');
if( opt.parent().val() == 'New' )
opt.next().attr("selected", "selected");
// Show the Option
var opt = $('option[value=New]');
opt.css('display','');
