问题描述
我尝试使用javascript禁用我的特定引导选择选项。
I attempt to disable my specific bootstrap select option using javascript.
我知道如何禁用常规选择选项,但是在使用引导选择时它没有用(已禁用/灰色,但我仍然可以选择)
在这里 jsfidle
I know how to disable "normal select option", but when using bootstrap select it just didnt works (its disabled/greyed but i can still choose it) here jsfidle
<select name="dropdownBranch" id="dropdownBranch" class="selectpicker" data-live-search="true">
<option value="0">Choose Number</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
</select>
<select id="pureDropDown">
<option value="0">Choose Number</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
</select>
<button onclick="disableDropdown()">disable</button>
function disableDropdown(){
var selectobject;
selectobject=document.getElementById("dropdownBranch").getElementsByTagName("option");
selectobject[3].disabled=true;
selectobject=document.getElementById("pureDropDown").getElementsByTagName("option");
for(z=0;z<selectobject.length;z++){
selectobject[z].disabled=true;
}
}
我也尝试删除特定选项并发生相同的情况(正常下拉菜单有效,但引导选择无效)
i try to remove specific option too and the same case happen (work on normal dropdown but not work on bootstrap select)
推荐答案
如此处,您需要在更改选项的禁用属性后重新呈现选择器。
As described here, you need to re-render the select picker after changing the disabled property of an option.
这应该可以解决问题:(JSFiddle)
This should do the trick: (JSFiddle)
function disableDropdown(){
var selectobject;
selectobject = document.getElementById("dropdownBranch").getElementsByTagName("option");
selectobject[3].disabled = true;
$('#dropdownBranch').selectpicker('render');
}
