如何设置Jquery panzoom 默认缩放？

Question

我想根据需要设置它的默认缩放

请告诉我如何更改我无法使用此插件找到的默认缩放值 API？请帮忙？谢谢

这是我的HTML

<section id="focal1">
<div id="dd2">

<div class="buttons1">
        <button id="zoominbtn1" class="zoom-in-1">+</button>
        <button id="zoomoutbtn1" class="zoom-out-1">-</button>
        <input type="range" class="zoom-range-1" style="position: absolute; margin-top: 2px; background-color: cornsilk;">
        <button id="restbtn1" class="reset-1" style="margin-left: 254px;">Default Zoom</button>
      </div> 
      <div class="parent1" >
        <div class="panzoom1">
<div id="belowpart">    

<img src="" usemap='#searchplot' class='searchplot_css' title='searchplot' alt='searchplot' id='img-searchplot' />
<map id='searchplot' name='searchplot'>

</map>

</div>
</div>
</div>
</div>
    </section>

这是全景缩放功能 JS:

(function() {
        var $section = $('#focal1').first();
        $section.find('.panzoom1').panzoom({
          $zoomIn: $section.find(".zoom-in-1"),
          $zoomOut: $section.find(".zoom-out-1"),
          $zoomRange: $section.find(".zoom-range-1"),
          $reset: $section.find(".reset-1")

        });
      })();

我在初始化后立即调用 zoom() 或者在选项中为 startTransform 设置一个值？我想要默认值为零，而且当加载图像时也应该缩小如何做到这一点？

Answer 1

初始化后立即调用zoom()

$elem.panzoom("zoom", 1.1, {silent: true})  // +10%

或在选项

中为startTransform设置一个值

$elem.panzoom({
    //...
    startTransform: "scale(1.1)"  // +10%
})

编辑：

(function() {
    var $section = $('#focal1').first();

    var elements = $section.find('.panzoom1');

    // initialize
    elements.panzoom({
        startTransform: 1.0,  // = no zoom
        $zoomIn: $section.find(".zoom-in-1"),
        $zoomOut: $section.find(".zoom-out-1"),
        $zoomRange: $section.find(".zoom-range-1"),
        $reset: $section.find(".reset-1")
    });

    // set new zoom value with animation
    elements.panzoom("zoom", 2.0, { animate: true });  // = 200%
})();

像这样改变你的功能

(function() {
        var $section = $('#focal1').first();
        $section.find('.panzoom1').panzoom({
          $zoomIn: $section.find(".zoom-in-1"),
          $zoomOut: $section.find(".zoom-out-1"),
          $zoomRange: $section.find(".zoom-range-1"),
          $reset: $section.find(".reset-1"),
          startTransform: "scale(1.1)"

        });
      })();
