我有几个下拉列表,根据我的选择和一些必要的计算,我希望能够自动选择值另一个下拉列表名单。我之前配置过的方式是使用文本框而不是下拉菜单,但是我的项目需求需要我切换到下拉列表。基于文本框输入使用jQuery在下拉列表中选择选项
这是我的方式当使用文本框有:
var minusOne = ["19","23","201","202","205","206","215","216","217","224","225","226","228","238","237","245","246","247","248","249","250","251","73","207","208","209","210","211","212","213","214","203","227","309","1302","134","135","136","142","762"];
var plusOne =["37"];
$("select[title='Crop Year']").change(function() {
var year = Number($(this).val());
var crop = $("select[title='Crop'] option:selected").text().split(' -');
var index = $.inArray(crop[0],minusOne),
indexII = $.inArray(crop[0],plusOne);
//TEXT BOX
index >= 0 ? $("input[title='RY']").val(year-1) : indexII >= 0 ? $("input[title='RY']").val(year+1) : $("input[title='RY']").val(year);});
现在我想//文本框下方的部分更改为下拉列表中。这是我迄今为止没有运气的尝试:
........
//DROP DOWN - Option I
if (index >= 0){$('select[title="RYTest"]').find(year-1).attr('selected','selected');}
else if (indexII >= 0) {$('select[title="RYTest"]').find(year+1).attr('selected','selected');}
else {$('select[title="RYTest"]').find(year).attr('selected','selected');}});
//DROP DOWN - Option II
if (index >= 0) {$('#LookupID option[text="' + year-1 + '"]').prop('selected',true);}
else if (indexII >= 0){$('#LookupID option[text="' + year+1 + '"]').prop('selected',true);}
else {$('#LookupID option[text="' + year + '"]').prop('selected',true);}});
我真的很感谢这里的任何帮助。我只是想让你知道,我不能在这个列表中添加或删除选项(没有.prepend($('')等),这个下拉列表从SharePoint列表中获取它的信息。 #LookupID并选择[标题= “RYTest”]是相同的元素。
