I have the above jQuery .each() that outputs the attached HTML to the console. In this case I want to extract the val() of only the input elements either of type text or type number. Is there some way to isolate just the input elements so I can get their values out into an array?

Thanks in advance...

回答1:

To extract number :

var arrNumber = new Array();
$('input[type=number]').each(function(){
    arrNumber.push($(this).val());
})

To extract text:

var arrText= new Array();
$('input[type=text]').each(function(){
    arrText.push($(this).val());
})

Edit : .map implementation

var arrText= $('input[type=text]').map(function(){
    return this.value;
}).get();


回答2:

Assume if all the input elements are inside a form u can refer the below code.

 // get all the inputs into an array.

    var $inputs = $('#myForm :input');

    // not sure if you wanted this, but I thought I'd add it.
    // get an associative array of just the values.
    var values = {};
    $inputs.each(function() {
        values[this.name] = $(this).val();
    });


回答3:

$.each($('input[type=number]'),function(){
  alert($(this).val());
});

This will alert the value of input type number fields
