javascript - javascript 函数在 jquery $(document).ready 中不起作用

Question

<script type="text/javascript" charset="utf-8" language="javascript">
    //Slider Function
    function projectrefinesearch() {
        alert('yes');
        var SliderSelectedMinPrice=$('#SliderSelectedMinPrice').val();
        alert(SliderSelectedMinPrice);
        var SliderSelectedMaxPrice=$('#SliderSelectedMaxPrice').val();


        if(SliderSelectedMinPrice!=''){
            postdata+='&minprice='+SliderSelectedMinPrice;
        }
        if(SliderSelectedMaxPrice!=''){
            postdata+='&maxprice='+SliderSelectedMaxPrice;
        }

        $.ajax({
            url:'<?php echo SITEURL; ?>ajax.php',
            data:postdata,
            type:'POST',
            beforeSend:function() {
                $('#newloader').show();
            },
            success: function(output) {
                $('#newloader').hide();
                $('.left_content_part').html(output);
            }
        });
    }

    $(document).ready(function(){
        $('#priceslider #jslider-left').mouseup(function(){
            var val=$('#Sliderprice').val()
            var init=0;
            var a=val.split(";");
            init=a[0];
            //alert(init);
            document.getElementById("SliderSelectedMinPrice").value=init;
            projectrefinesearch();
        });
    }
</script>

在 init 中获得价值后，它是预算的价格滑块（您可以在此处查看http://www.indianpropertyoption.com/p/search-projects/resultdocument.getElementById("SliderSelectedMinPrice").value ），并且projectrefinesearch();无法正常工作。 document.getElementById("SliderSelectedMinPrice")仍然null。请帮帮我

将 javascript 函数保持在就绪函数之外，如下所示：

 $(document).ready(function(){
    var one =  $("#someid").val();
    var two =  $("#someid2").val();

    Hello(one,two);
});

function Hello(one,two){
  alert("I am here"+one);
}
