Question

我想计算以下声明中的字词：

<pre id="output" class="output">["PHP","Python"]</pre>

然后我需要通过POST（提交按钮）将每个单词分配给PHP变量

当单词在[“”，“”]标签内时，我不知道如何计算PHP或JQuery？我有一个插件（无法编辑代码），如上所述填充预标签。

提前致谢

Answer 1

HTML：

<pre id="output" class="output">["PHP","Python"]</pre>
<form method="post" target="#" id="myForm">
    <input type="submit"/>
</form>
<textarea id="result" style="width:400px; height:200px;">
</textarea>

jQuery的：

//get rid of the brackets and split the vars with the comma as a delimiter
var varsArray= $("#output").html().split('[')[1].split(']')[0].split(',');

//count the elements:
var total = $(varsArray).length;

$(varsArray).each(function(idx,value){
    // the each function provides id and value, you use those to create a hidden field
    // in your form and set its name using the id, and value using the value 
    $("#myForm").append('<input type="hidden" name="var'+idx+'" value='+value+'>\n\r');
});

//print the new form's content into the text area just to see what it will look like
$("#result").val($("#myForm").html());

这里有一个jsfiddle的例子，我希望它有所帮助：

Answer 2

首先你需要得到pre的内容：

jQuery示例：

var contents = $("#output").html();

//now you could need to remove "[" and "]":

contents = contents.replace("[","").replace("]","");
var elements = contents.split(",");

//now you will have to check the length of "elements"

var count = elements.length;

计算<pre> tag using php or jquery</pre>中的字数
