我想选择所有下拉列表与从主下拉列表中选择的值相同。如果从主要下拉列表中选择了一个选项,我可以使用它,但如果有两个选项,我将无法使用它,我在下面添加了一些代码供您参考。
HTML:
<select name="ForceSelection" id="ForceSelection" onChange="javascript:return setDropDown();">
<option value="" selected>Select Name</option>
<option value="Pass">Pass</option>
<option value="Fail">Fail</option>
</select>
<select id="Qualifications" name="Qualifications">
<option value="select">select</option>
<option value="Pass">Pass</option>
<option value="Fail">Fail</option>
</select>
<select id="Qualifications" name="Qualifications">
<option value="select">select</option>
<option value="Pass">Pass</option>
<option value="Fail">Fail</option>
</select>
JavaScript:
function setDropDown() {
var index_name=document.QualificationForm.ForceSelection.selectedIndex;
document.QualificationForm.Qualifications.selectedIndex=index_name;
}
