Web front-end development control study notes jqgrid+ztree+echarts

As a web front-end beginner, today I want to record my experience in using three controls, namely the table control jqgrid, the tree control ztree, and the chart control echarts. They are described below.

1.jqgrid

First, let’s go to the official demo website, http://blog.mn886.net/jqGrid/. The above description is quite helpful.

The addition of jqgrid is relatively simple, that is, after downloading, place the js files and css files in the corresponding directories, and follow the instructions when using them

<link rel="stylesheet" type="text/css" media="screen" style="color: #000000">
      href="style/ui.gqgrid-bootstrap.css"/>

<script src="js%5Cgrid.locale-en.js" type="text/javascript"></script>

<br><span style="font-size: 14px">分别从相关目录下引用就可以了。<br>下边介绍一个简单的实例并且说下其中参数的设置<br></span>

<script type="text/javascript"><span style="color: #000000">
$(document).ready(<span style="color: #0000ff">function<span style="color: #000000">(){

});
<span style="color: #008000">//<span style="color: #008000">navgrid用于设置toolbar
$("#list4").navGrid('#gridPager'<span style="color: #000000">,
{

view:<span style="color: #0000ff">true,poition:"left",cloneToTop:<span style="color: #0000ff">false<span style="color: #000000">
}
);
});
</script>

There are currently two main problems. One is about the page layout, that is, weight and height often fail to constrain the table, and there are unexplained lines. At the same time, the use of scroll bars is also strange. The second is browsing. The problem with the navigation bar is that it cannot be adjusted with the layout of the table, and problems often occur such as running around and only displaying parts.

Fixed an issue where two horizontal scroll bars were displayed

<!--此行代码用来解决有两个横向滚动条的问题  -->
  $("#jqGrid").closest(".ui-jqgrid-bdiv").css({ "overflow-x" : "hidden" });

　Ideally, the effect I want to achieve is like this, with a table and a navigation bar below

<span style="color: #008080">85             </script>

I don’t quite understand the content of navGrid yet, so I’ll make a new summary next week.

Another thing is to use the data format json. When controlling, use the id with the same name as the json to control.

jqgrid Let’s stop talking about it here first, and then talk about it with new understanding.

It represents the tree structure by creating new nodes under the parent node. First set the setting and znodes respectively at the beginning, and then use the initialization function init to put the setting and znodes as initialization parameters for initialization.

There are two main problems that need to be solved now. One is that the tree structure is gone, all text appears in the same column, and there is no indentation. The second is how to reference json data for control instead of direct input. Post it when it's solved.

Let’s talk about two other things. One is that the location for adjusting the tree style is in the demo.css file. There is an option of ztreedemo. Change it to the name you want to use, and use class in

Just quote it.

The second one is the style of the entire tree, just modify the a tag in the ademo.

The third one is echarts. Frankly speaking, this plug-in is the most enjoyable to use among the three.

Attach the official website address first: http://echarts.baidu.com/.
To quote this plug-in just

That’s it.

Attached is the simplest implementation first.

I won’t explain anything else. Let me introduce how to use color change, which is itemstyle->normal->color, and then set up a colorList, put the color list into it in order, and then the colors will be displayed in the chart in order. But I don’t have much skill in js. I will discuss other functions in detail after thorough research.
