我对 JavaScript 很陌生,对 JavaScript 中的数组有疑问。直截了当:我有 HTML 代码:
<input type="text" name="conPrice" id="conPrice" size="16" maxlength="128"/>
<input type="text" name="OverP" id="OverP" size="16" maxlength="128" />
<div id="slider"></div> //Slider
数量的第一个字段,从滑块中拉出。SQL 表中价格的第二个字段
SQL基于有四个字段的条件:
| ID | MIN | MAX | PRICE |
我试图根据我的滑块值在字段OverP中获取价格列价格。因此,例如,如果我在滑块上有数字 6,并且它在 1-7 之间作为 MIN 和 MAX,那么价格将为 10。
我有这个 SQL:
<?php
$x = mysql_query("SELECT p_max AS max FROM dsd_price");
$y = mysql_query("SELECT p_min AS min FROM dsd_price");
$z = mysql_query("SELECT p_price AS price FROM dsd_price");
while ($x_array = mysql_fetch_array($x)){$max[] = $x_array;}
while ($y_array = mysql_fetch_array($y)){$min[] = $y_array;}
while ($z_array = mysql_fetch_array($z)){$price[] = $z_array;}
?>
最后是我的 JS:
<script>
$(document).ready(function slider() {
$( "#slider" ).slider({
value:1,
min: 0,
max: 201,
step: 1,
slide: function( event, ui ) {
//Its setting the slider value to the element with id "conPrice"
$("#conPrice" ).val(ui.value);
}
});
});
$(document).ready(function calcul() {
var frm = document.dsd_form;
var quant = frm.conPrice;
var overp = ['<?php echo implode("','", $price); ?>'];
var mini = ['<?php echo implode("','", $min); ?>'];
var maxi = ['<?php echo implode("','", $max); ?>'];
for(index = 0; quant > mini[index], quant < maxi[index]; index++){
$( "#OverP" ).val( overp[index] );
})
}
</script>
我没有得到我希望的结果,我知道问题出在我的 JS 上。希望尽快对我的话题提出一些建议。
更新:到目前为止放入测试页面的整个代码。滑块确实滑动,滑块值正在处理为 conPrice,但计算不起作用...
