jQuery addOption and selectOptions

问题

I have to deal with some old Javascript code that is throwing an error at addOption and selectOptions

Error: Object has no method selectOptions

Can someone explain me why is it not working? I am using jQuery 1.3

$("some_id").addOption(nodeId, nodeName); // add to list
$("some_id").selectOptions(/^~~/i, true); // clear selection

I solved the addOption line by this

$("some_id")[0].options.add( new Option(nodeName,nodeId));

but I'm still stuck with selectOptions error.

UPDATE just found out the application is also using Dojo. Could that be the problem? Are these methods Dojo specific?

Thanks!

回答1:

use Jquery Append to add options like this

$("yourid/class here").append($("<option></option>").attr("value", youroption-value).text(youroption-text));

try this, you can write your own methods:

$.fn.addOption = function(optText, optValue){
    var option = new Option(optText, optValue);
    return this.append(option);
};

$.fn.selectOption = function(toSelect){
 var $option = this.find("option[value='"+toSelect+"']");    
    if($option.length > 0){  
        //if option with the value passed on found then select it      
        $option.prop("selected","selected");
    }else{
        alert("option not found");
    }
};

var $select = $("#selectOption");
$select.addOption("Dummy1",2);
$select.addOption("Dummy2",3);

$select.selectOption(231);

Finally found whats wrong with it. These methods come from a jquery plugin by TexoTela. Why would someone do that just for select boxes?? Beats me

Thanks everybody for the responses. They taught me something indeed.
