JavaScript-Retrieve Multiple Values from DropDown

[Thakur Sachin Singh]

Hello All

i want to retrieve more than one selected value from the dropdown in javascript code but unable to retrieve more value, can anyone give me the idea??

please give me suggestion.

As a dropdown can have only one selected value, I'm not sure what "other" value you'd want to retrieve.

Or are you talking about a select-list rather than a dropdown?

[Thakur Sachin Singh]

yes i m talking about select list. can you give me any idea?

[Bear Bibeault]

Well, you can loop through the list of options and collect the values of the ones with the selected attribute.

Or you can make your life easier and use jQuery: the expression $('mySelectList').val() will result in an array of all the selected values.

actually i do not know the JQuery so will focus on java script. please see my below code. is this code wrong? from this code i am not retrieving values.

var lmaOther=document.getElementsByName("desirousLmaOther");
	var lmaOthers;
	var j=0;
	for(var i=0;i<lmaOther.length;i++){
	   
		if(lmaOther[i].selected){
	   	   lmaOthers[j]=lmaOther[i].value;
	   	   j++;
	   	  
	  	}
   	}

here lmaOther.length return value only 1 and lmaOther[i].selected gives undefined, any idea when these value come?

[Eric Pascarello]

Because

var lmaOther=document.getElementsByName("desirousLmaOther");  

is a reference to the SELECT element, not the OPTIONS

var lmaOther=document.getElementsByName("desirousLmaOther").getElementsByTagName("option");

P.S. jQuery is JavaScript.
