php - Jquery 在表单提交之间隐藏/显示

Question

我有一个由循环吐出的表单，其目的是以可管理的方式显示车辆库存，因此您可以编辑其中的任何内容我的问题是，当我单击隐藏/显示时，它会提交表单，并且由于是空的，因此会将我重定向到主页

它曾经有效。当我允许我的代码从 google 获取 jquery 时它实际上有效我确信这不是根本问题，但它似乎解决了它

这是我的表单代码

<?php
function manage_vehicles($soldvalue)
{
    $actual_link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
    echo '<div class="span12">
    <a href=""><button id="deleteall" name="deleteall" class="btn btn-danger" type="submit" >Delete</button></a> &nbsp;';
    if ($actual_link == 'http://localhost/cardealerwins/admin.php?manage_vehicles')
    {
        echo '<a href="admin.php?manage_sold"><button href="admin.php?manage_sold" id="managesold" name="deleteall" 
        class="btn btn-success" type="submit" >Manage sold vehicles</button></a>';
    } 
    else if ($actual_link == 'http://localhost/cardealerwins/admin.php?manage_sold')
    {
        echo '<a href="admin.php?manage_vehicles"><button href="admin.php?manage_vehicles" id="managesold" name="deleteall" 
        class="btn" type="submit" >Manage active vehicles</button></a>';
    }
    echo '</div>';
    //get the total number of vehicles active in the database to loop through them and displaying them to manage
    $query = mysql_query("SELECT COUNT('auto_id') FROM `auto` WHERE `sold` = $soldvalue");
    $all = mysql_result($query, 0);  //store the value so we can run this loop accordingly
    $counter = 1;
    $auto_id = 0; //auto id equal to zero as starting point, it will increase randomly to as many vehicles it will diplay
    while ($counter <= $all)  //ie run for every car
    {
        $fields = 'auto_id, year, make, model, engine, sound_system,mileage, price, vin, att1, att2, att3, att4, att5, att6, att7, att8, 
        att9, att10, att11, att12, att13, att14, att15, picture1, picture2, picture3, picture4, picture5, picture6, picture7, picture8, 
        picture9, picture10, picture11, picture12';
        //check where the auto id is greater then the previously one according to $auto_id which increments
        $data = mysql_fetch_assoc(mysql_query("SELECT $fields FROM `auto` WHERE `auto_id` > $auto_id AND `sold` = $soldvalue"));

        $auto_id = $data['auto_id'];  //here is the magic, we set the auto id to the current one being spitted out so it follows through
        //now with all the $data retrieved from the database we can print car by car with its unique info and ids
        echo '<div id="displaycarwrap" class="span3 container">

        $counter++; //used for the while loop it self and for classes id uniqueness for javascript
    }

?>

这是我的 jquery 代码:

//function to hide the extra info for the cars in manage vehicles
(function ($) {
    $.fn.showHide = function (options) {

    //default vars for the plugin
        var defaults = {
            speed: 250,
            easing: '',
            changeText: 0,
            showText: 'View details',
            hideText: 'close'

        };
        var options = $.extend(defaults, options);

        $(this).click(function () {
// optionally add the class .toggleDiv to each div you want to automatically close
                      $('.toggleDiv:hidden').slideUp(options.speed, options.easing);
             // this var stores which button you've clicked
             var toggleClick = $(this);
             // this reads the rel attribute of the button to determine which div id to toggle
             var toggleDiv = $(this).attr('rel');
             // here we toggle show/hide the correct div at the right speed and using which easing effect
             $(toggleDiv).slideToggle(options.speed, options.easing, function() {
             // this only fires once the animation is completed
             if(options.changeText==1){
             $(toggleDiv).is(":visible") ? toggleClick.text(options.hideText) : toggleClick.text(options.showText);
             }
              });

          return false;

        });

    };
})(jQuery);



$(document).ready(function(){

   $('.show_hide').showHide({
        speed: 250,  // speed you want the toggle to happen
        easing: '',  // the animation effect you want. Remove this line if you dont want an effect and if you haven't included jQuery UI
        changeText: 1, // if you dont want the button text to change, set this to 0
        showText: 'View details',// the button text to show when a div is closed
        hideText: 'Close' // the button text to show when a div is open

    });




});

我的控制台告诉我:

Uncaught ReferenceError: google is not defined 

我认为这与此无关

Uncaught ReferenceError 的错误

Uncaught ReferenceError: google is not defined

您正在使用的显示/隐藏按钮默认用作提交按钮。事实上，任何<button>表单中的元素将在单击时提交表单。

尝试改变

    <button class="show_hide btn btn-mini icon-th-list" href="#" rel="slidingDiv'. $counter .'">View details</button>

to <input type="button"> 

其他属性完好无损

(或者)或者，将此代码添加到您的 jquery 中，以便默认禁用提交

$('.show_hide').click(function(e){
     e.preventDefault();
});
