SelectPicker - Select option Live search if the result doesn't match by bootstrap-select

问题

I want to display other for default and enable to select. The case is if we type and didn't match between the result and option.

$('.selectpicker').selectpicker({
     noneResultsText: 'I found no results'
});

<select class="selectpicker" data-live-search="true" >
    <option value="other">other</option>
    <option>Alabama</option>
    <option>Alaska </option>
    <option>Arizona </option> 
</select>

How to condition value="other" will show if didn't match between result and option?

回答1:

I modified bootstrap-select.js to accommodate that behavior;

I inserted this line of code after the search event, this would search for the option with "Other" in its data attribute and will always display it.

    var defaultOption;

    that.$lis.find('a').each(function(){
      // console.log($(this).data("normalized-text"));

      if($(this).data("normalized-text").indexOf("other") >-1){
        defaultOption = $(this);
      }
    });

    defaultOption.parent().removeClass('hide').show();

I minified the script below. Do run the snippet.

!function(e){"use strict";function t(e,t){return e.toUpperCase().indexOf(t.toUpperCase())>-1}function i(t){return e.each([{re:/[\xC0-\xC6]/g,ch:"A"},{re:/[\xE0-\xE6]/g,ch:"a"},{re:/[\xC8-\xCB]/g,ch:"E"},{re:/[\xE8-\xEB]/g,ch:"e"},{re:/[\xCC-\xCF]/g,ch:"I"},{re:/[\xEC-\xEF]/g,ch:"i"},{re:/[\xD2-\xD6]/g,ch:"O"},{re:/[\xF2-\xF6]/g,ch:"o"},{re:/[\xD9-\xDC]/g,ch:"U"},{re:/[\xF9-\xFC]/g,ch:"u"},{re:/[\xC7-\xE7]/g,ch:"c"},{re:/[\xD1]/g,ch:"N"},{re:/[\xF1]/g,ch:"n"}],function(){t=t.replace(this.re,this.ch)}),t}function
