Examples of conversion between jQuery objects and DOM objects and strings

The following editor will bring you an example of conversion between jQuery objects, DOM objects and strings. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor and take a look

1. String---------->jQuery object

$(HTML string): $('

I am a little flower of the motherland

')

To be added list

##2 , jQuery object---------->DOM object

Subscript selection method (principle: jQuery is the array form of DOM):$("h2") [1]

Use the .get(index) function

3. String ----------->DOM object

Write a script function

function parseDom(nodelist) { //nodelist是html文本字符串
 var objE = document.createElement("p"); 
 objE.innerHTML = nodelist;
 return objE.childNodes;
}

First put the 'string'--->jQuery---->DOM object

4. DOM object--------->String

Use the function .html()## in jQuery

#$(Selector).html();//Use the selector to select the DOM object you want to convert into a string, and then use the html() function and it’s done
