将默认值设置为jquery范围滑块

Question

我试图将默认值设置为jquery范围滑块，但它不适合我。我在php数组中有值并在范围滑块中使用它我想选择默认值我有以下代码：

$sum = $wpdb->get_results("SELECT `sum_insured` FROM `{$wpdb->prefix}dh_insurance_plans_rates` WHERE `plan_id` IN (SELECT `id` FROM wp_dh_insurance_plans WHERE `product`='$product_id') GROUP BY `sum_insured` ORDER BY CAST(`sum_insured` AS DECIMAL)");
?> 
var SliderValues = [<?php
                $s = 0;
                foreach($sum as $suma){
                $s++;   
                echo $sumamount = $suma->sum_insured;
                if($s < $wpdb->num_rows){
                echo ', ';
                }
                } ?>];
$(function () {
    $("#sum_slider").slider({
        range: "min",
        min: 0,
        max: SliderValues.length - 1,
        step: 1,
        slide: function (event, ui) {
            $('#coverage_amount').text(SliderValues[ui.value]);
            $( "#coverage_amount" ).val( "$" + SliderValues[ui.value] );
        }
    });
    $( "#coverage_amount" ).val( "$" + $( "#sum_slider" ).slider( "value" ) );
});

Answer 1

我想尝试改变滑块的最大值。而不是“max：SliderValues.length - 1”...使用像：

max: SliderValues[SliderValues.length - 1]

Answer 2

我自己就是这样做的：

var selct_value = SliderValues.indexOf;

和使用

value: selct_value,
